2012 Republican Presidential Candidate, Rick Santorum | featured news

Two new polls in the showdown state of Michigan suggest that Rick Santorum failed to gain a badly needed shot of momentum in Wednesday night's Republican presidential debate.

Rick Santorum’s acknowledgment of voting for No Child Left Behind threatened to undercut his message that he is the unimpeachable conservative in the Republican nominating contest.

The last time the four remaining contenders in the GOP presidential race met on a debate stage, all eyes were on Newt Gingrich, who was trying to ride the momentum off his surprise victory in South Carolina.

Rick Santorum says he won't back down from a speech in which he said Satan was targeting the U.S.

Rick Santorum and Mitt Romney competed over conservative credentials and faced tough questions from voters in Arizona and Michigan on Tuesday.

The battle for the Republican presidential nomination heads into a potentially decisive phase over the next two weeks with contests in 13 states that could finally answer some of the questions that have defined the race.

A resurgent Rick Santorum hopes to spring his next big surprise in Michigan. Newt Gingrich looks for a campaign revival in the Bible Belt. Mitt Romney has his home state of Massachusetts, and the luxury of picking his spots elsewhere, if not everywhere, as the race for the Republican presidential nomination roars back to life.

Newt Gingrich hedged whether he could win his old home state on Super Tuesday as he campaigned through the vote-rich Atlanta area with Herman Cain at his side amid incursions from Mitt Romney and a surging Rick Santorum.

CNN has canceled plans for a GOP presidential debate on March 1, after Mitt Romney and Rick Santorum indicated they would skip the event. "Without full participation of all four candidates, CNN will not move forward with the Super Tuesday debate," CNN said in a statement.

A political group supporting Mitt Romney’s Republican presidential bid began airing television advertisements in Michigan today, charging that rival Rick Santorum is a “big spender” and “Washington insider” who backed letting convicted felons vote.
