The GOP candidates on stage in Orlando.
ORLANDO, Florida (CNN) - The leading Republican presidential candidates intensified their fight over who has the true conservative credentials in sometimes contentious debate Sunday night.
A more aggressive Fred Thompson compared Rudy Giuliani’s social positions with Democratic frontrunner Hillary Clinton, and implied Mitt Romney once held more liberal stands than Senator Ted Kennedy.
Asked if Romney and Giuliani has convinced him they were consistent conservatives, the former Tennessee Senator said, “Well, we've got an hour and a half. Maybe they can work on it.”
Giuliani tried to turn the tables on Thompson, saying, “you know, Fred has his problems, too. I mean, Fred was the single biggest obstacle to tort reform in the United States Senate. He stood with Democrats over and over again. …Fred Thompson, along with very few Republicans, blocked tort reform over and over and over again. That is not a conservative position.”
Defending his own record a day after finishing near the bottom of a conservative voters straw poll, the former New York City mayor, said, “I think it was good conservative record. I think, in every case, you can always find one exception or two to someone being absolutely conservative or absolutely this or absolutely that, but I think I had a heck of a lot of conservative results.”
In another skirmish, Senator John McCain, R-Arizona, blasted Romney for claiming to be the only real Republican in the field. He said, “Governor Romney, you've been spending the last year trying to fool people about your record. I don't want you to start fooling them about mine. I stand on my record. I stand on my record of a conservative, and I don't think you can fool the American people. I think the first thing you'd need is their respect.”

Romney continued his criticism of Giuliani over spending and taxes, saying, “we're not going to keep Hillary Clinton out of the White House by acting like Hillary Clinton. Now, I'm proud of my record. Not just of the words, but of the record of the governor of Massachusetts. Like Mayor Giuliani I had a tough state to be running in. I was a conservative Republican in a very Democrat state. My legislature, 85 percent Democrat. We face a $3 billion budget gap. We solved it without raising taxes, without adding debt.”
Thompson joined the direct attack on Giuliani, criticizing his stand as mayor on immigration, abortion and gun control. He said Giuliani “sides with Hillary Clinton on each of those issues I just mentioned.”
Asked his concern over Romney’s record, Thompson said. “You've just got a minute?”
Meanwhile, after watching the top candidates in the Republican presidential field attack each other in the opening minutes of Sunday night’s debate, Mike Huckabee played above the fray.
Huckabee, left out of the early skirmishes between candidates running ahead of him in the polls, said as he was called on. “ Let me begin by saying, for the first time in about nine debates, I'm kind of glad I wasn't in on the first few minutes because it was all about these guys fighting each other.”
To laughter, the former Arkansas governor said, “I am more than content to let you let them fight all they want tonight, shed each other's blood and then I'll be ready to run for president because I'm not interested in fighting these guys.”
