Republican Presidential Candidate | featured news

Newt Gingrich has stormed to an upset victory over Mitt Romney in the South Carolina GOP primary with a pair of strong debate performances that most voters said was important to their choice.

As South Carolina Republicans begin voting in the first primary of the south today, GOP insiders say that all the candidates have had their problems in Palmetto State, one reason why today's outcome has been so hard to predict.

With the crucial Republican presidential primary in South Carolina just hours away, front-runner Mitt Romney on Friday lowered expectations for how well he will do and acknowledged he is in a neck-and-neck race with Newt Gingrich.

He blasts the moderator for asking a question about an ex-wife and then trades sharp jabs with Rick Santorum and front-runner Mitt Romney. With time ebbing to catch front-runner Mitt Romney, the Republican presidential candidates brawled Thursday night in a debate that drew angry denunciations of the media from Newt Gingrich and spurred heated disagreements between Gingrich and fellow challenger Rick Santorum.

Dredging up a past that Newt Gingrich has worked hard to bury, the GOP presidential candidate's second ex-wife says Gingrich asked for an "open marriage" in which he could have both a wife and a mistress.

Texas Gov. Rick Perry on Thursday dropped out of the race for the Republican presidential nomination and endorsed Newt Gingrich, adding a fresh layer of unpredictability to the campaign two days before the South Carolina primary.

On a separate issue, Gingrich told reporters that he paid 31 percent of his 2010 income in taxes, more than double the 15 percent Romney said he pays. A Gingrich spokesman said the 31 percent was the effective federal rate on his income. Gingrich declined to criticize Romney on the tax issue, saying instead that it made the case for his own proposal to put in place an optional 15 percent flat income tax. "My goal is not to raise Mitt Romney's taxes, but to let everyone pay Romney's rate," he said.

"Super PACs" have spent about $27.5 million to influence the presidential election, a good chunk coming from an independent group supporting GOP front-runner Mitt Romney.

Former Massachusetts governor Mitt Romney told reporters on Tuesday he currently pays taxes "close to the 15% rate" and that most of his income comes from investments... His net worth is estimated to be between $190 million and $250 million, according to his personal financial disclosure report.

When Jon Huntsman announced his campaign for president last summer, he received the type of media attention that presumed he would be an immediate and formidable challenger for the Republican nomination.
