There are also three Senate seats left to declare and seven governorships. But those results could take some time. That concludes our live coverage on what has been a night to forget for the Democrats - but one to savour for the Republicans.
BBC North America editor
writes: Mr Obama's fall from grace has been hard and fast. He has been pulled to Earth by an electorate that is deeply divided, by a politics that has become tidal.
The Republicans have won 54 House seats, equalling Bill Clinton's mid-term pummelling in 1994. With more than 20 seats still to declare in this throw-the-bums-out election, the outcome's only likely to get worse for Obama and the Democrats.
Looming large over this poll has been the figure of Tea Party Mama Grizzly-in-chief Sarah Palin. The former Alaska governor was not running for election, but she endorsed dozens of candidates. Feverish speculation that the "hockey mom" who turned the flank of the Republican establishment will now run for the White House in 2012 is not likely to recede.
David Smith from Austin, Texas, writes: President Obama completely mis-read his 2008 victory. His election was not a mandate to implement socialist policies (i.e., nationalisation of health care). The majority of Americans who voted for him wanted him to implement positive change... change that would improve the economy, increase jobs, and reduce the government debt. He's accomplished none of these things. Instead, he's acted like a drunken sailor, increasing spending, programs, taxes, the deficit and the debt, and doing nothing to improve the lives of Americans who really just want the basic necessity of life... a job.
Another Republican winner was Michele Bachmann, a photogenic Tea Party heroine, who held her seat in Minnesota's sixth district. During Obama's White House campaign, she suggested he espoused anti-American views.
Karen Lee, from San Jose, California, writes: It is sad how gullible and easily manipulated most Americans are. How quickly they forget that it was the Republicans who got us into this mess by de-regulating "big government" (control over the financial houses) in the first place! It's understandable that they are unhappy that the Dems didn't do enough or the right things to improve the economic situation, but putting the Republicans back in power certainly isn't going to help, it will make things worse.
Tonight we also saw Democrats bag a rare beast of the American electoral jungle: the endangered Republican incumbent. Anh Cao, a former Jesuit seminarian who became the first Vietnamese-American Congressman, lost his seat in New Orleans to Democrat Cedric Richmond. Even his recent declaration of "love" for Obama couldn't save him.
The longest-serving member of the House, 84-year-old Democrat John Dingell, won a 29th term in Michigan's 15th district. Dingell, first elected in 1955, said this year's was the nastiest campaign he'd ever seen.
Another notable Republican winner was Steve King, in Iowa's 5th district, who said earlier this year he could "empathise" with a man who flew a plane kamikaze-style into a Texas tax office.
Tom Jensen of Public Policy Polling
tweets: "I think Hispanics in NV may be the toughest demo group in the country to poll. Everyone (us included) screwed it up in 08 and this year" and later "Polling in Spanish would probably help with the Hispanics in NV but I wonder if they're a harder group to reach even beyond that"
To say expectations were high when Obama came to office is a bit of an understatement; some seemed to think he'd part the waters of the Potomac and lead the liberal faithful to the Promised Land. Can he recapture the magic, or is he now a lame duck leader?
Have your say.
It's hard to believe that in 2008 political obituaries were being written for the Republican Party, after the Democrats won the White House and both Houses of Congress. Just two years later, conservative champagne corks are popping again.
The Democrats have taken a kicking, but it doesn't mean Obama's finished, of course. Reagan looked on the ropes when Republicans lost 26 House seats in 1982, but romped to a second term two years later. And Bill Clinton seemed to be twitching on the canvas when the Democrats lost 54 House seats in his mid-term shellacking. It's way too early to tell if Obama's going to be a two-term president, such as Clinton and Reagan, or a one-termer like Jimmy Carter and George Bush Snr. We'll find out in 2012.
In California, Proposition 23, a ballot initiative funded by oil companies seeking to suspend the Golden State's landmark greenhouse gas regulations, has failed.
Another notable Republican win was Joe Barton's in Texas' sixth district. Barton was widely criticised for apologising to BP's chairman over government pressure placed on the oil giant in the aftermath of the Gulf oil spill.
Victorious Democratic Senate leader Harry Reid says: "Today Nevada chose hope over fear. Nevada chose to move forwards, not backwards."
Still no result in one of the year's hardest-fought contests, for the Florida governor's mansion. It's going down to the wire between Republican businessman Rick Scott and Democratic state chief financial officer Alex Sink.
Democrat Mike McIntyre holds his North Carolina House seat, beating Tea Party-backed challenger Ilario Pantano, an ex-Marine who once fired 60 rounds into two unarmed Iraqis. (Murder charges were dropped against Pantano, who said the Iraqis had been about to attack him.)
tweets: All the big money has come from the big GOP stalwarts. Will it collide with the grassroots movement that is the Tea Party?
Ryan Lizza of The New Yorker says: Nobody has ever won an election saying, "it would have been a whole lot worse if my policies weren't implemented".
Matt Bai of the New York Times
writes: If there is a lesson in all this for both parties, perhaps it's that merely piling up votes on Election Day doesn't confer on you a mandate for any ambitious agenda - unless you have presented the voters with the difficult choices you intend to make. For Republicans, this argues against over-interpreting the meaning of Tuesday's gains. For Mr Obama, it probably means that the campaign for the next agenda begins right now.
Maverick Democrat Dennis Kucinich - who tried to impeach Dick Cheney over the Iraq war, and who once questioned George W Bush's mental health because of the former president's sabre-rattling over Iran - holds on to his seat in Ohio's 10th district.
Another notable Republican gain was Mississippi's first district. Once-popular Travis Childers, rated as one of the most conservative Democrats, lost his seat to Republican challenger Alan Nunnelee, a state senator from Elvis's hometown of Tupelo.
Gene Taylor, who took the ploy of Democrats distancing themselves from Obama to a whole new level by claiming he'd voted for John McCain in 2008, has lost the Mississippi fourth district seat he held for 21 years to Republican challenger Steve Palazzo.
Dave Weigel of Slate
tweets: If Murkowski wins in AK after O'Donnell, Fiorina and Raese lost, this is quite the night for Palin.
The BBC's Peter Bowes in Los Angeles says: True to form, California voters have bucked the national trend and rejected the state's highest-profile Republican candidates. Perhaps they were turned off by the ultra-high spending political novices from Silicon Valley? Or perhaps they simply feel it is too early to give up on Obama's vision of hope?
Florida's 2nd district has elected a Republican for the first time. Ousted Democrat Allen Boyd had been endorsed by the National Rifle Association, but it wasn't enough to stop Tea Party-backed political newcomer Steve Southerland.
Rich Iott, the Ohio Tea Party candidate who dressed as a Waffen SS soldier for a hobby, has lost his election bid. Democrat Marcy Kaptur saw him off to hold on to her seat in the ninth district (which includes Toledo, home of Joe the Plumber).

tweets: I count a combined 128 years in the House between Spratt, Boucher, Skelton, Edwards, Pomeroy. All defeated tonight
Moderate Republican Cory Gardner ousts freshman Democrat Betsy Markey from Colorado's fourth district.
Political consultant Laura Schwartz
tells BBC World Service: "People are voting against the president today, they are voting against the present Congress today, and it's time for Obama to hit that reset button and do something in the next two years to bring folks back." She also says she thinks Marco Rubio is the next big thing. "Right now he is the man of the moment, but he could make that moment last longer if he arrives in Congress ready to take a leadership position. I think he could become and incredible leader."
JRC, in Gainesville, Florida, writes: This is a remarkably clear referendum on Obama's policies. Had he demonstrated even the slightest degree of bi-partisanship, he would probably have maintained a unified government. If he'd given his socialist healthcare plan to anybody besides Nancy Pelosi this would be a completely different election result.
tweets: This is a town that is built on relationships. The question is can John Boehner work with Harry Reid and with President Obama?
Senator John Kerry releases a statement: "Politico was wrong, Huffington Post was wrong, hell, all the pundits were wrong. Harry Reid isn't just Dracula, he isn't just Lazarus, he's our Leader and our whole caucus is thrilled that he's unbreakable and unbeatable."
BBC North America editor
says: The Tea Party's two most eccentric candidates have lost their races, and perhaps cost the Republicans a couple of scalps. But make no mistake, the conservative wing of the Republican Party is now a power in the land. This is hugely difficult for the president. While there will be much talk of compromise and reaching deals, the explicit aim of many Tea Party supporters is to block and undo Obama's agenda.
President Obama has called Republican leaders John Boehner and Mitch McConnell, telling them he's "looking forward to working with them and the Republicans to find common ground, move the country forward and get things done for the American people".
tweets: Two years ago we were writing the obits for the Republicans. Tonight - a revival.
The BBC's Katie Connolly
tweets: Reid's win proves he can get voters to the polls - that vaunted "turnout" operation. Important for Obama in 2012
Eric Barlow, in Fairfax, Virginia, writes: The Democrat leadership showed arrogance and contempt for the constitution and the American people. I am an independent voter and my vote sent a message to our politicians that they will need to listen to the people. If the Republicans don't listen to us they will be gone next time too.
Possible reasons why Sharron Angle lost in Nevada: she said she favoured abolishing the US education department; wrongly claimed two US towns were under threat of Sharia law; asked by a group of Hispanic students why her ads seemed to cast Latinos in a negative light, she told them: "Some of you look a little more Asian to me"; the list goes on.
Californians reject a ballot initiative to legalise the consumption, cultivation and trade of marijuana.
Ben Quayle, son of gaffe-prone former Vice-President Dan Quayle, wins the race for the open seat in Arizona's third district. One of Quayle Jr's campaign ads branded Obama "the worst president in history".
For many conservatives, Senate leader Harry Reid is one of the three baleful heads of a Cerberean blob known as Obama-Reid-Pelosi. With unemployment in the state hovering above 14%, Nevada should have been an open goal for the Republicans. But Tea Party-backed challenger Sharron Angle lagged as the spotlight focused on her personal views.
tweets: Republicans won back both of NH's House seats tonight, but failed to win any seats in Maine or Massachusetts.
Harry Reid, Senate Majority Leader, holds his Nevada seat.
The Republicans seize control of the House of Representatives.

Ed Henry from CNN
tweets: President Obama called John Boehner to congratulate, according to senior Dem official
Republican National Committee chairman Michael Steele says: "Tonight, we learned that our democracy is alive and well and that voters, not politicians, will be the ones who direct the course of our great nation."
Republicans will be cock-a-hoop at grabbing Obama's old Illinois Senate seat. Winner Mark Kirk embellished details of his naval career, wrongly claiming he'd been named intelligence officer of the year. He also erroneously said he'd come under fire while flying over Kosovo and Iraq. Democratic loser Alexi Giannoulias, meanwhile, was hit by allegations the bank his family owned had links to organised crime.
Senate results still to come - Nevada, Colorado, Washington and Alaska.
Ex-eBay boss Meg Whitman, the defeated California gubernatorial candidate, pressure-hosed more than $160m of her own cash into the most expensive non-presidential campaign in history, outspending her rival nearly 10 times over. But it was all for nought.
Arizona Republican Governor Jan Brewer, who approved the state's tough new immigration law, defeats her Democratic challenger.
the new independent governor for Rhode Island, tells the BBC World Service he's not too optimistic that Democrats and Republicans will be able to work well together effectively: "They seem to fall back into their partisan trenches like World War I."
Barack Obama's former Senate seat in Illinois is won by Republican Mark Kirk.
The BBC's Andy Gallacher in Florida says: Marco Rubio may not have reclaimed America yet but he has in part reclaimed Florida, a vital state in any political contest. A new star is born, watch this space.
Evelyn, in Georgia, writes: Tonight's results are a reaction to the state of the US economy, the lack of jobs, the deficit, illegal immigration, border control, and healthcare reform which was shoved down our throats, just to name of few. However, the Republicans need to understand this is not an endorsement for them. They are just being given another chance to turn things around, as Obama"s "change" isn't working.
Obama will be sorely disappointed by the Ohio gubernatorial result. With his eyes on 2012, the president wanted a friend in the statehouse in this key Midwestern state, which swings like Tarzan. As former CBS anchorman Dan Rather once said: "The situation in Ohio would give an aspirin a headache.''
Jackie Calmes and Megan Thee-Brenan of the New York Times
write: Women have been among the Democrats' most loyal supporters, giving them a majority of their votes in all but one of the past 14 election years. But the size of that traditional advantage appears to have narrowed this year. Since 1982, when exit polls first measured support, Republicans only once received the same share of women's votes as Democrats - in 2002 - and Democrats lost their narrow Senate majority that year.
Ousted Ohio Governor Ted Strickland had seen jobs haemorrhage in his state. His attempts to undermine the credibility of John Kasich, an ex-Fox News presenter, over his role as managing director of the collapsed Lehman Brothers bank, clearly didn't wash with voters.
Eric Schultz, communications director for the Democratic Senatorial Campaign Committee e-mails reporters to say: "Republican shadow groups spent $5.8 million in their unsuccessful attempt to defeat Senator Boxer - including $1 million from Karl Rove's Crossroads GPS, and $3.9 million from the US Chamber of Commerce."
Democrats maintain their hold on the Senate. They now have 50 of the 100 seats. Vice-President Joe Biden has a casting vote.
John Kasich defeats Governor Ted Strickland in Ohio and seizes control for the Republicans of a state deemed crucial to the 2012 presidential election.
Damien Paletta of the Wall Street Journal
writes: Republican Lou Barletta's defeat of Rep. Paul Kanjorski (D., Pa.) could have a direct impact on the Obama administration's future economic policy. The 13-term Democrat was expected to play a central role in the government's efforts to overhaul the country's mortgage-finance system and Fannie Mae and Freddie Mac.
Democrat Ike Skelton is out after more than 30 years in Congress, losing his Missouri seat to Sarah Palin-endorsed Republican Vicky Hartzler.
Jerry Brown wins a major victory for Democrats in California's governor race, beating Republican Meg Whitman.
The only two Muslim congressmen (both Democrats) have been re-elected. Keith Ellison won in Minnesota, despite Tea Party calls for him to be defeated because of his faith. And Andre Carson held his Indiana seat, amid Republicans' attempts to portray him as a Sharia law advocate.
Former US Senator Lincoln Chafee becomes the first independent to be elected Rhode Island governor.
Republican Pat Toomey wins Pennsylvania's Senate race, defeating Democrat Joe Sestak.

Democratic Senator Barbara Boxer is re-elected in California, beating Republican former Hewlett-Packard executive Carly Fiorina.
House Leader-elect John Boehner tells cheering crowds the night is a repudiation of Washington. Boehner's had a rancorous relationship with the Obama White House. His robin's-egg blue eyes are prone to floods of tears in emotional House-floor speeches.
The Jersey Shore district saw more drama in recent weeks than, well, an episode of MTV reality show Jersey Shore. Runyan, an ex-football star, accused a Tea Party candidate of being recruited by Democrats as a spoiler. Republicans demanded a criminal investigation.
Republican Jon Runyan unseats Democrat John Adler in New Jersey's third district.
Lynn Sweet of the Chicago Sun Times
writes: Chicago mayoral hopeful Rahm Emanuel was the architect of the House Democrats' 2006 victories which resulted in Nancy Pelosi becoming Speaker of the House. Emanuel, then the chairman of the Democratic Congressional Campaign Commitee, on Tuesday night saw his work undone, as CNN predicted that the Republicans will retake the House. So what is Emanuel doing Tuesday night? Quipped an aide: "He's with friends and a bottle of Jack Daniels."
Veteran House Democrat Barney Frank wins a 16th term in Massachusetts. The House Financial Services Committee chairman won by a margin of 68% in 2008. But this time he had to lend his own campaign $200,000 to see off a Republican political novice, Sean Bielat.
Holly, in Shelburne, New Hampshire, writes: President Obama has tried to support programmes that help the middle and lower class but the Republican rich are trying to wrest control from him and the Democrats to return the country to the disparity of wealth that grew at such levels under President Bush. It is sad that a country of our size cannot have a health or social security programme that is stable.
By winning 180 seats, the Republicans have now exceeded their pre-election seat tally in the House. From now on, every seat they win will be an improvement on their 2008 performance.

The BBC's Rajesh Mirchandani in Las Vegas says: Tea Party favourite Sharron Angle sent a last-minute e-mail to voters around 3pm local, saying exit polls showed a tie and that her supporters should get out in the last few hours and make the difference in this crucial Senate race.
In New Hampshire, Democratic Representative Carol Shea-Porter has lost her seat to Manchester's Mayor Frank Guinta. Ms Shea-Porter was one of those Democrats who unexpectedly won in the landslide 2006 election. It's not a huge surprise that she lost, but it does break the Democratic monopoly in New England.
The BBC's Laura Trevelyan in New York says: Early returns suggest at least three tight races in upstate and suburban New York, where Republicans hope to oust sitting Democrats. If centrist Republicans make gains here, they would provide a balance in Congress to the radical Tea Party newcomers.
The BBC's Rajesh Mirchandani in Las Vegas says: A power outage at a polling station in Clark County (which contains Las Vegas and is a Democratic stronghold) delayed the closing of polls, as did long lines at some locations.
CNN's Soledad O'Brien
writes: Despite record election achievements by African-Americans in the House, the United States Senate will not have an African-American in its ranks. All three black Senate candidates, Kendrick Meek (D-FL), Alvin Greene (D-SC) and Mike Thurmond (D-GA) are projected to lose tonight. The only incumbent black senator, Roland Burris (Ill.-D), is retiring.
Newton, in Green Bay, Wisconsin, writes: Wisconsin is a very conservative state. If you have ever been here, you would not be so amazed that Feingold has lost.
Wisconsin is a big loss for the Democrats. Staunch liberal Feingold is famous for spearheading Senate efforts to reform campaign finance rules. He voted against the hugely unpopular 2008 banks bailout, but that couldn't save him. Winner Ron Johnson's first involvement in politics, he's said, was to visit a Tea Party meeting last year. Johnson, who styles himself a "citizen candidate", has attributed climate change to sunspots.
Ross, in San Francisco, writes: This goes to show that US politics will continue to be swayed by the mobilised fringes - liberal or conservative. With the usual poor voter turnout, Tea Partiers, such as Rand Paul, who has publicly stated a refusal to reach across the aisle, are going to gridlock progress.
Republicans capture their fourth Senate seat from the Democrats as incumbent Democrat Russ Feingold in Wisconsin loses to polyester magnate Ron Johnson.
Just nine Senate seats remaining. So far Democrats have 48, and Republicans 43. The latest: Oregon for the Democrats and Idaho for the Republicans.
Marc Ambinder of The Atlantic
tweets: A Republican points out to me that the GOP establishment won most of its primaries in the Midwest and is cleaning up there.
Republican Senator Bob Bennett, who was ousted at the Utah Republican convention by a Tea Party favourite, told BBC World Service that his "sin" was voting with President Bush and John McCain on the financial rescue package, known as Tarp. "People said you wasted $700bn. I said no we haven't, we'll get the money back, we've averted a financial catastrophe. I was right but that didn't make any difference."
New Orleans TV Station WWLTV
reports that Republican Congressman Joseph Cao has been unseated by Democrat Cedric Richmond. He was the sole Republican in the House to vote in favour of President Obama's healthcare reform legislation.
Polls close in several states, including keenly watched California and Washington, on the hour.

Representative Joe Wilson - who shouted "you lie!" at President Obama during the latter's healthcare address to Congress - has won his race for re-election in South Carolina's second district.
PS: Nikki Haley replaces Republican Governor Mark Sanford, who was notoriously nabbed going AWOL to tango with a mistress in Argentina.
South Carolina's new governor Nikki Haley, who was endorsed by Sarah Palin, strenuously denied during the campaign having had two extra-martial affairs. Haley is the daughter of Indian Sikh immigrants; a state senator who was supporting one of her opponents in the primary was widely criticised after calling her a "raghead".
tweets: Looking at the Tea Party, a number of Republicans I've talked to have looked across the pond and said we need inclusive people, like PM Cameron.
Texas Republican Bill Flores has ousted veteran Democrat Chet Edwards from the Lone Star state's 17th district. As well as Waco, the district includes the town of Crawford, where a certain George W Bush lives on a ranch.
Republican Nikki Haley becomes South Carolina's first woman governor.
Former Republican Senate hopeful
says the message from the people of New Hampshire is "loud and clear - we need limited government, fiscal responsibility, and national security". However he tells the BBC World Service: "Elected officials are going to be under a very tight leash, and if they don't do what they campaigned to do, and that is to fundamentally change course, they are not going to be in office two years from now. This is a citizen rebellion..."
Rus Sundholm, in Fort Wayne, Indiana, writes: The biggest issue is the way our government is run. Congress, which is supposed to represent the people, represents those who provide them the most money for their re-election. It doesn't matter if they are Democrats or Republicans, they are out for themselves, not to do the right thing for their constituents.
Emma, Northfield, Minnesota, writes: The US is generally more conservative than other Western countries, even with a Democrat-controlled government. Compared to many European leaders, President Obama is quite moderate - not the extreme liberal Republicans try to make him out to be.
Senate races in Pennsylvania, Illinois and Colorado are turning out to be very close. Democratic candidates are narrowly ahead in all three races, with some precincts still to report.
Exit polling conducted by ABC News shows that voters are self-identifying as Democrats and Republicans in equal numbers - 36% a piece. Independents remain the big unknown, but in House races, they seem to be opting for Republicans by a very large margin: 15 percentage points. Obama won independents in 2008 by 8 points, and the last time Republicans had an advantage this large was in 1982, when independents broke for Republicans by a 14-point margin.

South Carolina voters elect the first black Republican to Congress from the Deep South since the Civil War's aftermath. Tea Party-backed Tim Scott defeated Democrat Ben Frasier.
PS: When first elected in 2006, Governor Deval Patrick was criticised for spending $11,000 on drapery for his statehouse suite and upgrading his ride to a Cadillac. PPS: During the 2008 presidential campaign, Obama denied claims he'd plagiarised part of a speech by Patrick.
Republican Tom Corbett defeats Democrat Dan Onorato in Pennsylvania's gubernatorial race. History was on Corbett's side: the governor's mansion in the state has switched parties every eight years since 1954 and the trend continues.
Governor Deval Patrick's win in Massachusetts will cheer Democrats. Sometimes called "mini-Obama", Patrick was the first African-American to take the Bay State governor's mansion. He beat a stiff challenge from Republican Charles Baker, a former health insurance boss.
The BBC's Rajesh Mirchandani in Las Vegas says: A man who voted Sharron Angle told me it was because he wanted to "get rid of the bums in Washington". The next man said, "I listened to Sharron Angle and realised I had to vote... for Harry Reid. Angle's too extreme." It's a bitter-fought race and Nevadans seem to be voting not for who they like most, but the candidate they dislike least.
Dr Carol Swain of
on the BBC World Service: "Most Americans will describe themselves as conservative and I think the policies of the Obama administration, not just the economy, have been so far to the left... I believe that's why the Republicans have been doing so well. It's a repudiation of the president, and also of his political appointees."
BBC contributing analyst Ted Koppel says: Both Reagan and Clinton had popularity numbers that were lower than President Obama right now. It's a mistake to draw too many conclusions from the numbers of a president in an off-year election.
Democrat Deval Patrick bucks the anti-incumbent trend to hold on to the Massachusetts governor's mansion.

Re-elected Texas Governor Rick Perry deployed some political jujitsu to beat a strong challenge from former Houston mayor Bill White. Most newspapers in the Lone Star state endorsed White. But Perry leapt on the anti-incumbent band wagon, even though he himself is an incumbent, and avoided debates with White.
Craig, in Beaverton, Oregon, writes: Two years ago we were promised "change" when we voted Obama in. Nothing's changed. I, and many others here in the USA are sick of it. When the government doesn't do what it's supposed to do, we throw them out. Come the next election, if the Republicans don't do their jobs we'll throw them out with the same gusto.

Barack Obama, the man who gave America an oratorical head massage two years ago, has seen his approval ratings slide into the basement. He seems about as popular as a sub-prime mortgage lender on Skid Row right now. But it's not unusual for the party of a sitting president to lose seats mid-way through his first-term.

BBC North America editor
says: The fact that the Republicans haven't taken the Delaware, West Virginia or Connecticut Senate seats suggests to me they won't formally take control of the Senate. But there will be plenty of "blue dog" (right-wing) Democrats in the Senate, looking over their shoulder and voting with the Republicans.
Bruce Feist, in Herndon, Virginia, writes: I'm primarily concerned with our government's inability to act. Obama had to fight tooth and nail to get healthcare reform passed, and now it's in danger of further attack. I want the government to get back to the people's business, instead of perpetually bickering in preparation for the next election.
West Virginia Democratic Senate winner Joe Manchin vowed independence from President Barack Obama, even showing off a photo of him in the Oval Office with George W Bush and running a campaign ad showing him shooting a bullet through a copy of the cap-and-trade bill.
Democrat Joe Manchin wins his West Virginia Senate bid, beating Republican John Raese.
Carl Paladino also offered only a grudging apology for sending racially charged e-mails to friends, including one of Barack and Michelle Obama as a pimp and prostitute. Another, entitled "Proof the Irish discovered Africa", contained a video of monkeys jigging to Lord of the Dance.
New York's gubernatorial loser Carl Paladino did himself no favours by comparing trade unions to pigs; calling for welfare recipients to live in prisons, so they could learn about personal hygiene; and branding gay parades "disgusting".
Matt, in Philadelphia, writes: Democrats want to install a European-style socialist state. The only problem is that European politics do not work in the US. Just as Western democracy cannot work in the Middle East.

Veteran lawmaker Rick Boucher of Virginia's ninth district has lost his seat to Republican Morgan Griffith. Mr Boucher, who represents coal country, was a key negotiator on the climate change bill that passed the House but not the Senate. Climate change is a touchy issue in Mr Boucher's part of the country, and even though he won concessions for the coal industry, he had a hard time explaining his pro cap-and-trade vote to his constituents. This result is a repudiation of Mr Obama's climate change agenda and will make lawmakers very wary to touch the issue again before 2012.

tweets: Tom Perriello, who lost, was one of the few Dems who came out of the closet and ran on his record of voting with Pres Obama.
Republican Rob Hurt ousts Democrat Tom Perriello from Virginia's 5th district. Perriello beat a six-term incumbent in 2008, in a district even Obama failed to carry during the Democratic landslide of that year. But Perriello's vote for healthcare reform may have cooked his goose.
The BBC's Kevin Connolly in Wheeling, Illinois, says: Still no concrete news from the party of Republican Mark Kirk, who's bidding to take Barack Obama's old seat in the Senate in Illinois. The music hints at the mood and the expensive nature of American politics. "Dancing in the Moonlight" followed by "If I Had a Million Dollars".
Republican cardiologist Larry Buschon wins the open seat of Indiana's eighth district, held by the Democrats for the past four years. He beats Trent Van Haaften.
Joanne Kennedy in Boston, Massachussets, writes: I voted for the first time tonight as a new US citizen. Why vote? Maybe my one vote could make a difference and stop these far right Tea Party people.
Former Homeland Security Secretary Tom Ridge on the BBC World Service: "As a Republican I am quite pleased with some of the preliminary results, but the real challenge will come in January with the new Congress, a whole new group of governors, and the responsibility to try and deal with some of the problems about which they had been critical."
The Connecticut Senate campaign was particularly bitter. Victorious Democrat Richard Blumenthal had to apologise for having "misspoke several times" when he suggested he'd served in Vietnam. Linda McMahon, a former wrestling executive, body slammed him over the claim, branding him a liar. She splurged more than $40m of her own dough on the race.
Rikkie, Lakewood, Ohio, writes: The recession has played a dominant role. Pity that the majority of Americans do not understand that it is a global recession and no one leader or nation can be held accountable or indeed be expected to turn it around.
Leading Florida newspaper The Orlando Sentinel
has called Florida's 8th Congressional District for Republican challenger Dan Webster. Mr Webster unseats liberal favourite Alan Grayson, who rose to prominence with his ardent support for health care reform. Liberal radio host Nicole Sandler tweeted: "We lose the wonderful @AlanGrayson in the House. I'm sick."
tweets: What's so great about US elections are these larger than life figures. Linda McMahon was CEO of WWF but in the end she was just too tough.
Arkansas's ousted Senate incumbent Blanche Lincoln was one of the most moderate Democratic senators, but that was no longer enough in a year when Southern Democrats are as endangered as the Yangtze River Dolphin. The Republican winner, John Boozman, wants to abolish the tax-collecting Internal Revenue Service and repeal Obama's healthcare reforms.

Florida's victorious Senate candidate, Marco Rubio, surfed the anti-Obama wave to keep the Sunshine State for the Republicans. The race has been a disaster for once-popular Charlie Crist, who took the gamble of quitting as Florida's governor to run for Senate.
The BBC's Rome Hartman, executive producer of World News America, says: Christine O'Donnell may not be headed for the Senate, but she certainly has provided reporters and late-night comics with a lot of material!
LN Rock, who blogs as
African American pundit
tells the BBC World Service that the Democratic Party didn't get its message out fast enough. "The president has not been able to communicate with the American people, saying what he has accomplished over the past two years. He tackled healthcare reform as his first strategy priority and he didn't communicate to the American people that it was a critical priority and get a wellspring of support in the American populace."
Delaware's defeated Republican House candidate Glen Urquhart once baffled historians by claiming the phrase "separation of church and state" - commonly associated with Thomas Jefferson, the third US president - had actually been coined by Adolf Hitler.
In another bright spot for the Democrats, John Carney has beaten Tea-Party backed Republican Glen Urquhart to win Delaware's only House seat.

says: New York voters still have just under an hour to vote. Scattered reports of problems at polling places around the city, but nothing compared with those on primary day, when many polling places opened late and there was widespread confusion over the new electronic voting system. Complaints from those who say they missed voting on two ballot initiatives because they were printed on the back of the ballot.
BBC North America editor
says: Tea Party supporter Christine O'Donnell's defeat in Delaware will provide evidence to those in the Republican establishment who are wary of the movement. They will say that with a more mainstream candidate, they would have taken the seat. But perhaps the oddest of her views and statements had little to do with conservative Tea Party economics. She just was a bit of a flaky candidate. Still, if it costs Republicans the Senate, the argument will rage on.
Christine O'Donnell also memorably began a campaign ad with the statement "I'm not a witch", possibly the first politician to do so since the 17th Century mayoral race for Salem town hall.
JD, in Nevada, writes: Obama might be loved in Belgium, but he's loathed in every part of America that is not a large urban city. Europe will not understand the results, because they don't understand the premise. America has been written off many times in the past 200 years, but it's very self-cleansing. Tonight you'll hear a massive flushing sound for the left.
In the Republican primary, Ms O'Donnell beat Mike Castle, a moderate Congressman who was seen as a sure-fire winner for the Republicans. Karl Rove called her "nutty" and unelectable. And so it came to pass. O'Donnell's warnings about the dangers of mouse-people and masturbation practically gift-wrapped the race for Democrat Chris Coons.
Gabriele, Fort Collins, Colorado, says: It's disappointing to think that the Republicans may gain ground so soon after the elections two years ago. America is very close to voting itself into a third world state.
No surprise that the Democrats held on to Delaware's open Senate seat, which was vacated by Vice-President Joe Biden. But this could be the defeat that prevents the Republicans capturing control of the Senate. And their woefully misjudged pick of Tea Party heroine Christine O'Donnell is to blame.
Craig Goldman, in Scottsdale, Arizona, says: The biggest election issue for me is US support for Israel. I feel the administration is sending the wrong message to the Middle East with President Obama's lack of public Israeli support.

says: House Leader (at the moment) Nancy Pelosi, has just spoken urging people still to get out the vote, saying, "We are not going back to the failed policies of the past," and adding that she believed there would be "a great Democratic victory". Optimism is a wonderful quality.
Courtney N, in Vilonia, Arizona, says: I do not identify with one particular party. However, at the moment the Congress and the Senate are grossly out of balance. We need to find our balance again in order to recover and begin to move forward.
Democrat Christopher Coons easily wins Delaware's Senate race, beating Tea Party-backed Christine O'Donnell.
Bruno Maiolo, in Linden, New Jersey, says: One of the most important things the government must tackle is the uncertainty that everyone feels. From taxes to the new health plan this uncertainty is preventing companies from hiring. This is keeping the unemployment rate high meaning people are being very cautious with their spending. Bottom line is the economy.

Rose, in Watertown, Massachusetts, says: I'm absolutely astonished that Americans can't understand how much government does in their everyday lives, and continue to expect a quick fix even though Obama and the Democrats have managed significant changes, while dealing with massive economic crises left over from the Bush era.
Alvin Greene, the defeated South Carolina Democrat, baffled everyone by winning the party's Senate nomination earlier this year, despite running no visible campaign whatsoever. One of Greene's ideas to revive the state's economy was to launch an industry making, err, action dolls of himself.

says: CNN's first early, raw, exit poll suggests Democratic Governor Joe Manchin will win the Senate race in West Virginia. Good news for Obama if true? Not so much: Manchin campaigned against cap-and-trade and other presidential policies. Even if the Senate doesn't go Republican, there may be one more conservative Democrat there.
US comic Scott Capurro gives BBC World Service his view of the election: "I think the Democrats are going to get wiped out in this election, and I say good, they've wasted so much good will - it's like Eddie Murphy in every movie since Dream Girls."
South Carolina's re-elected Senator Jim DeMint recently said gay people or unmarried women who sleep with their boyfriends should not be allowed to teach in schools. He also once said that if Republicans could derail healthcare reform it would be Obama's Waterloo.
Nathan Erkkila, in Salt Lake, Utah, writes: As a liberal, I believe that if a Democrat gets voted out, then it is most likely their doing, but I am more concerned about politics on the state level, such as governor.
Democrats are on full-scale alert for a conservative tsunami. Some commentators predict we're going to witness something special this year: a once-in-a-lifetime Democratic cataclysm - the American political equivalent of seeing Halley's Comet.
Jason Goodwin, in Montgomery, Alabama, writes: I really don't expect much of a difference, regardless of who the majority party is. Just about all of them will say whatever they want to say in order to get elected. Then, once they're in office, they serve themselves and not the people they represent.
Democrats spent little money on their candidate, Lee Fisher, in the Ohio Senate race as Republican Rob Portman, a Bush administration trade director, was so far ahead in pre-election polls.
The BBC's Kevin Connolly says: As projected results begin to pour in from elsewhere, in Wheeling, Illinois, where Republican Senate candidate Mark Kirk is waiting to party, an example of American ingenuity - broadcasters have been struggling to cope with the noise made by a man equipped with a spike on a three-metre pole who's been bursting balloons that stray up to the ceiling of the hotel ballroom. He's been issued with a rubber suction device on a pole. Result: silent balloon recovery and rescue.
No surprises, but South Carolina's incumbent Senator Jim DeMint has cruised to re-election. He's been the patron of many of this year's Tea Party candidates.
Republican Rob Portman coasts to an easy victory in Ohio's Senate race.

If Rand Paul hadn't have won Kentucky, Republican hopes for Senate control would've been dashed. The ophthalmologist was lambasted this year for criticising the 1964 Civil Rights Act, which abolished discrimination against African-Americans. Mr Paul has also said he favours changing the US constitution to ensure the children of illegal immigrants do not become US citizens.

Indiana's Senate seat was a must-win for the Republicans. Little money was spent on the campaign of Dan Coats's Democratic opponent because Coats was so far ahead. PS: Obama was the first Democratic presidential candidate to take Indiana for 44 years back in 2008.
Tea Party-backed Republican Rand Paul wins Kentucky's Senate race; Republican Dan Coats wins Indiana's Senate race.
Conservative news site The Daily Caller
reports that it has exclusive Senate exit polling indicating: "Republicans are up in the Kentucky, Florida, Illinois, Missouri, Pennsylvania, and Wisconsin senate races. But the exits show GOPers down in West Virginia, Connecticut, Colorado, Nevada, California and Washington State."
A recent AP poll suggested as many as one in three US voters was not firmly committed. And as George Bush Snr once said: "It's no exaggeration to say that the undecideds could go one way or another."
Early exit polling in Kentucky suggests that strong anti-Obama sentiment is fuelling votes - around 41% of people claim they are casting their ballot to show opposition to the president. Democrats once harboured hopes of picking up an open Senate seat there, but with numbers like those, the chances of Jack Conway beating Rand Paul are slimmer than ever.

Joon Sae Park, in Walnut Creek, California, says: The importance of this election has been tremendously overstated. Regardless of which seats are won and lost in the House and Senate, the policies of war and corporate exploitation will continue because these policies are supported by both parties. Americans who want real change should not vote for Democrats or Republicans.
The BBC's Kevin Connolly says: In Wheeling, Illinois, a scene being repeated in a thousand towns across America - balloons being inflated and television reporters in a deserted ballroom. Supporters of Senate candidate Mark Kirk are convinced this will be a victory party... if they're right, this will be a footnote to history - he'll be the Republican who took Barack Obama's old seat.
BBC North America editor
says: The ABC exit poll will make for gloomy reading in the White House but few politicians will take comfort from it. The poll portrays a country deeply ill-at-ease with its government. Some 62% say the country is seriously on the wrong track, 73% dissatisfied with the federal government, and 53% have a negative view of the Democrats. Oh, and 53% have a negative view of the Republicans. Only 25% approve of the way Congress is doing its job.
As ever, this American political cycle has been a satirist's treasure trove of outrageous gaffes, oddball antics and general meta-weirdness. As the results come in, we'll take a district-by-district look at some of the, ahem, interesting characters who've spawned a blizzard of Twitter hashtags this year.
John Grayless, in Kansas City, Missouri, writes: I live in a markedly Democrat neighbourhood with only a few conservative voters. This year the voter turnout has been far less than in the past 10 years. I haven't seen this kind of change in voter turnout since President Carter was up for re-election. It's obvious that Democrats are unsatisfied with the agenda President Obama has given is. The economy, housing, and jobs markets have all suffered from the lack of leadership.
We've got another result in from Indiana. Republican Dan Burton holds the fifth district with nearly 60% of the vote. The Hoosier State's all-red so far.
Mike Pence, chair of the Republican caucus in the House, holds his seat in Indiana's sixth district with a whopping 75% of the vote.
Robert Graham, in Metairie, Louisiana, writes: The tag line for this election is definitely "it's the economy!" My wife has been out of work for a year-and-a-half and I have no job prospects at all if something happens where I am working. We are literally one paycheck from disaster. Obama has had two years to get things going and he hasn't - all he has done is spend us to the brink of national bankruptcy.
The first result of the night has come in - an easy hold for Republican Congressman Hal Rogers in Kentucky's fifth congressional district.
The candidates have reached the top of the election rollercoaster. Now join us for the fastest part of the ride and remember to duck, just in case the people in the front car ate too much for lunch. One thing's for sure: the next few hours promise some vertical loops, twists and turns even more tortuous than this metaphor.

ABC News exit polling gives some insight into the minds of the voters. The 88% who think the economy is in a bad shape is a figure only 4% down from what it was in 2008. And, tellingly 73% describe themselves as dissatisfied about the federal government, with 26% saying they are angry.
Robert Reich, former Secretary of Labour in President Bill Clinton's cabinet, told the BBC World Service that although most people don't follow politics all that specifically, "they do they care about their own jobs, their wages, keeping their homes". He says historians will discuss the timing of Obama's healthcare reform.
Jaime King, Boise, Idaho, writes: It feels like we have a government more concerned with Wall Street balance sheets than the fact that millions of people are being turned out of their homes, the first waves of the unemployed are running out of benefits, massive cutting into higher education is forcing more than half of our undergrads to take on ruinous loans to pay for post-secondary education, crumbling infrastructure, massive imprisonment and people in general just seem worried, tired and scared because Washington is fiddling while the nation burns.
Dennis, Nashville, Tennessee, writes: Too many people here are angry, have no idea why they're angry, nor are they capable of discussing or presenting rational solutions to their problems, whether real or perceived.
Robert-Paul LeMay, Albuquerque, New Mexico, writes: Eight years of the Bush disaster and we now intend to blame Obama. About time this country woke up. No matter who runs this sinking ship of state, the glory days are over.

CNN has been zeroing-in on the battle in Alaska. It's a fascinating one. The Republican candidate Joe Miller could be beaten by the Republican-incumbent-turned-independent Lisa Murkowski.

The election is widely seen as a referendum on the first two years of Barack Obama's presidency.
