GOP Presidential Primary

Chicago Mayor and former Obama Chief of Staff Rahm Emanuel blasted Mitt Romney Monday night, saying the presumptive Republican nominee's economic policies "actually led to this crisis we've had."

Gingrich said Monday he would have to "reassess" his bid if he fails to place well in the state.

Vice President Biden delivered a speech on the Obama administration's efforts to preserve the Florida Everglades while Mitt Romney campaigned with Sen. Marco Rubio (R-Fla.).

Jon Huntsman stood behind the presumptive Republican nominee Monday, saying "of course" he would vote for Mitt Romney in a general election.

The Ex-NYC mayor once said Romney lacked a core, but now says he'll support him.

The six GOP candidates who dropped out of the presidential race may be gone, but they aren’t altogether forgotten.

Indiana Gov. Mitch Daniels all but took himself out of the running to become Mitt Romney's running mate.

Sen. Marco Rubio said he wanted to "respect the process" Romney has put in place to make a selection.

Mitt Romney may have earned an coveted endorsement this week from Mitch Daniels, but the Indiana governor is warning Romney that the current tone of his campaign is too negative.

"You have to campaign to govern, not just to win," Daniels told The Indianapolis Star.

The governor, himself considered a front-runner for the Republican presidential nomination before opting against a run last year, said of Romney's campaign that "political victories that follow 'slash-and-burn' campaigns seldom lead to great accomplishments."

One reason Ron Paul is continuing to fight for the Republican presidential nomination: He can afford to.

The Paul campaign announced Friday that it had raised $2.6 million in March alone and some $10.4 million in the first quarter of 2012 — numbers that become even more impressive considering that they came as Paul's chances of winning enough delegates to stop Mitt Romney's nomination became increasingly slim.

The campaign's nearly $1.8 million in cash on hand — and lack of debt — explain why Paul is continuing to spend on advertising buys in Texas and Rhode Island. The congressman is hoping to net a significant number of delegates from his home-state primary later this month.
