DAY IN A NUTSHELL
Mitt Romney followed his victory in Michigan with a single day's campaigning in South Carolina - where rivals John McCain, Mike Huckabee and Fred Thompson are pinning their hopes. Democratic candidates continued to campaign in Nevada, following Tuesday's debate in Las Vegas, with Barack Obama picking up the endorsement of the state's biggest newspaper.
"Is Barack Obama, then, the ideal Democratic candidate for president? Hardly. His policy recommendations - when he can be convinced to get any more specific than 'I represent change' - are the opposite of 'change.' They're old-line, welfare-state solutions that haven't spent enough time in the microwave to appear even superficially appetising."
Editorial in Las Vegas Review Journal, one of Nevada's most influential publications, as it (somewhat grudgingly) endorsed Mr Obama.
"Romney wins: If things keep going this way, John Edwards will win Nevada, Fred Thompson will win South Carolina, Rudy Giuliani will win Florida, and the two parties will have to dig up scores of new candidates to win the remaining states."
Chris Suellentrop, New York Times, on the still wide-open nomination races
"The voter-registration office here in Clark County [Nevada] says it received 4,025 new-voter registrations last week and 2,240 the week before that. In a presidential race where new voters are trending toward Barack Obama, and in a state where Saturday's Democratic caucus may attract no more than 50,000 people, those new voters could tip the balance."
June Kronholz, Wall Street Journal
"Mitt Romney finally won the 'gold' yesterday, as he so effusively puts it, and the result is a Republican Presidential battle that is more muddled than ever. The most important story out of Michigan is that Republicans are still looking for a standard bearer."
Editorial in Wall Street Journal
On the Democratic front, the latest national poll conducted by Reuters/Zogby has Hillary Clinton and Barack Obama neck-and-neck, with Mrs Clinton at 39% and Mr Obama on her tail with 38%. Edwards is a distant third, with 9%.
On the Republican side, John McCain leads with 28%, Mike Huckabee comes second with 23% and Mitt Romney - who won Tuesday's Michigan primary - follows with 13%.
But in Nevada - where both parties hold caucuses on Saturday - an American Research Group poll sees Mitt Romney out in front with 28%, Mr McCain in second position with 21% and Rudy Giuliani in third place with 11%.
Meanwhile, exit polls from Michigan produce some interesting nuggets. According to polls done for the Associated Press, evangelical voters - credited with carrying Baptist preacher Mike Huckabee to victory in Iowa - split evenly between him and Mitt Romney, a Mormon.
CNN's exit polls show 68% of black voters plumped for "uncommitted" rather than vote for Hillary Clinton, which may worry her campaign heading into South Carolina, where the black vote will be crucial.
