ORLANDO, Fla. (AP) - Face to face in confrontational debate, Republican presidential hopefuls Mitt Romney and Rick Perry sarcastically accused each other Thursday night of flip-flopping on Social Security and health care, flashpoints in their early struggle for the party nomination.
Romney accused Perry of having said the federal government "shouldn't be in the pension business, that it's unconstitutional," a reference to Social Security benefits.
The Texas governor disputed the charge, saying it "wasn't the first time Mitt's been wrong on some issue before." But Romney mocked his rival's denial, adding crisply, "You better find that Rick Perry and get him to stop saying that."
Perry soon returned the favor, saying that Romney switched his position on health care between editions of a book he had published. In one edition, Perry said, Romney advocated expanding the health care program he signed in Massachusetts to the rest of the country. "Then in your paperback you took that line out, so speaking of not getting it straight in your book, Sir."
"It's like badminton," said Perry.
The Massachusetts legislation required residents of the state to purchase health coverage or pay a fine, a cornerstone of the law that President Barack Obama won from Congress last year that has inflamed conservative voters across the country.
The two men run one-two in the public opinion polls - Perry ahead, Romney a close second - and compete daily for endorsements from members of Congress and other party luminaries in hopes of gaining a permanent edge before the caucuses and primaries begin early next year.
Perry gave no ground on one issue - his support for a state law in Texas that gives the children of illegal immigrants reduced tuition to state colleges and universities.
"If you say that we should not educate children who have come into the state for no other reason than they've been brought there, by no fault of their own, I don't think you have a heart," he said.
That drew a retort from former Pennsylvania Sen. Rick Santorum.
"No one is suggesting that students who are illegal in this country shouldn't go to colleges and universities," he said, adding that he objects to giving them state subsidies to do so.
"Most folks have to pay the full boat. ... Why should they be given preferential treatment as an illegal in this country?" he said.
In contrast to sometimes-harsh comments about each other, the GOP presidential hopefuls agreed Obama's handling of the economy was woeful. They said they would cut taxes, eliminate government regulations and take other steps to help create jobs in a nation with 9.1 percent unemployment.
"The president's party wants to take from some people and give to others. That isn't the way to lift America," said Romney.
Perry said his state ranked first in the country five years in the row in attracting businesses looking to relocate. "Something special happened there ... and we plan to keep it that way," he said.
Rep. Michele Bachmann of Minnesota told one questioner, "You should get to keep every dollar you earn," then backpedaled.
"Obviously we have to give money back to the government so we can run the government," she said.
The two-hour event was sponsored by Fox News and Google, in keeping with an emerging trend in which mainstream media organizations partner with Internet companies.
Without saying so, former House Speaker Newt Gingrich gave an endorsement of sorts to one of the elements of Obama's job proposals. Asked whether he would renew unemployment benefits for those out of work, he said they should be required to participate in a "business led" job training program. "I believe it is fundamentally wrong to give people money for 99 weeks for doing nothing," he added.
Obama has called for Congress to extend the current system of unemployment benefits, but he also wants to permit states to experiment with the type of training program that has been used in Gingrich's home state of Georgia.
Also on stage were Rep. Ron Paul of Texas, former New Mexico Gov. Gary Johnson, businessman Herman Cain and former Utah Gov. Jon Huntsman.
