G.O.P. Debate

"Trump drew audible boos from the stadium when he declined to rule out a third-party presidential

run -- a move that could seriously complicate the GOP's bid for the White House.

"I mean, this is what's wrong. He buys and sells politicians of all stripes. He's already hedging his bet on the Clintons, OK?" Kentucky Sen. Rand Paul cut in.

Trump responded by chastising the country for being too "politically correct."

"I've been challenged by so many people and I don't frankly have time for total political correctness," Trump quipped.

Moderator Megyn Kelly challenged Trump on some of his past comments about women. "You call women you don't like fat pigs, dogs, slobs and disgusting animals," she said.

Trump quickly responded: "Only Rosie O'Donnell," sparking laughter from the audience.

Immigration loomed large at the debate -- an issue that Trump claimed full credit for bringing to the nation's attention.

"If it weren't for me, you wouldn't be even talking about illegal immigration, Chris," Trump said to Fox host Chris Wallace.

 Bush, addressed the issue by stressing that he did not support "amnesty."

"We need to be much more strategic on how we deal with border enforcement, border security," Bush said. "We need to eliminate the sanctuary cities in this country. It is ridiculous and tragic that people are dying because of the fact that local governments are not following the law."

At one point, Christie and Paul tumbled over the issue of data collection after Paul said he was proud to stand for the Bill of Rights.

"Megyn, that's a completely ridiculous answer," Christie snapped. "I want to collect more records from terrorists, but less records from other people. How are you supposed to know?"

"You get a warrant!" Paul responded. 

Christie shot back: "You know, when you're sitting in a subcommittee just blowing hot air, you can say things like this."

When Paul criticized Christie for hugging President Barack Obama several years ago, Christie went for the jugular: "Senator Paul, you know, the hugs I remember are the hugs that I gave to the families who lost their people on September 11th." CNN
