Through the ups and downs of the Republican presidential campaign, Mitt Romney has remained in effect the front-runner.
He has done so even without holding as many rallies, town hall meetings or meet-and-greet events as some of the other candidates. He's also done fewer media appearances.
The top man in charge of President Barack Obama’s 2012 re-election bid says the campaign is taking a page out of the 2008 election playbook by focusing on mobilizing grassroots support in swing-states like Colorado.
As the Republican presidential candidates prepare for another debate, this one Saturday night in South Carolina, former House Speaker Newt Gingrich has been campaigning in New Hampshire.
He opened up his state headquarters Friday, buoyed by some recent polls that show his support increasing among Republican voters. A new CBS poll has him tied for second place with Mitt Romney, behind Herman Cain.
Republican presidential candidate and Texas Congressman Ron Paul is known for his fervent opposition to armed intervention overseas and the Federal Reserve — and for his equally fervent supporters.
And while those supporters may want him to be the next president for different reasons, they're all well aware that before entering politics, Paul was a doctor back in the southeast Texas district he represents in the U.S. House.
