DAY IN A NUTSHELL
It is John McCain's big night, as he formally accepts the Republican Party's candidacy for the White House. His speech - in which he pledges to bring change to Washington and tells how his experience as a Vietnam prisoner of war inspired his love of country - brings to an end the Republican national convention in St Paul. His wife Cindy, Senator Lindsey Graham and Governor Tim Pawlenty all praise his courage, integrity and character.
"Let me offer an advance warning to the old, big spending, do nothing, me first, country second crowd: change is coming."

"John has picked a reform-minded, hockey-momming, basketball shooting, moose hunting, salmon-fishing, pistol-packing, mother-of-five for vice president."

"Calling for more troops to be sent to Iraq was one of the most unpopular things John McCain could have done. Some said it was political suicide. But you know what? It was the right thing to do."
Senator Lindsey Graham praises Mr McCain for his stance on the Iraq war
"Tonight, John McCain said that his party was elected to change Washington, but that they let Washington change them. He's right. He admonished the 'old, do-nothing crowd' in Washington, but ignored the fact that he's been part of that crowd for 26 years, opposing solutions on health care, energy and education."
Bill Burton, Obama campaign spokesman, responds to Mr McCain's speech
"The notion that any questions about her work in Alaska is somehow not relevant to her potentially being vice president of the United States doesn't make too much sense to me... I assume that she wants to be treated the same way that guys want to be treated, which means that their records are under scrutiny. I've been through this for 19 months, she's been through it, what, four days so far."
Barack Obama, campaigning in Pennsylvania, dismisses the idea that scrutiny of Mrs Palin's record has been unfair
"We don't have a 'present' button as governor - we are expected to lead, we are expected to take action and not just vote 'present."

A new CBS survey suggests the race between Barack Obama and John McCain is neck-and-neck, with each polling 42% support among registered voters.
A poll conducted for CBS at the weekend had Mr Obama several points clear, at 48% to Mr McCain's 40%.
The latest daily tracking polls from Gallup and Rasmussen give Mr Obama a seven point and five point lead respectively over Mr McCain.
Meanwhile, some 37.2 million US television viewers tuned in to see Sarah Palin give her speech on Wednesday, Nielsen Media Research reports - only just over a million short of the record-breaking audience pulled in by Barack Obama last Thursday.
Some 38.4 million watched Mr Obama deliver the grand finale of the Democratic convention, thought to be the biggest audience ever for a US political convention speech.
Coverage of day three of the Republican event drew a large female audience, with 19.5m tuning in, compared with 14.3m who watched Hillary Clinton speak on the second day of the Democratic convention.
Mr McCain, giving the closing speech for the Republicans, was in competition with a big American football game, which may dent his viewer figures.
