JACKSONVILLE, Fla. — More than a million Hispanic voters are the prize as Republican presidential rivals Mitt Romney and Newt Gingrich resume campaigning after a feisty, final debate before Florida's GOP primary.
Romney was the aggressor in the second debate in four days Thursday night, pressing Gingrich to apologize for an ad labeling him as anti-immigrant and calling the idea "repulsive."
Both men arranged for appearances Friday in Miami with the Hispanic Leadership Network on the day after the debate. The state has roughly 1.5 million Hispanic voters, who figure to play prominently in next Tuesday's Florida primary.
Immigration sparked the first clash Thursday night, moments after the debate opened, when Gingrich responded to a question by saying Romney was the most anti-immigrant of all four contenders on stage. "That's simply inexcusable," the former Massachusetts governor responded.
Gingrich fired back that Romney misled voters by running an ad accusing the former House speaker of once referring to Spanish as "the language of the ghetto." Gingrich claimed he was referring to a multitude of languages, not just Spanish.
Romney initially said, "I doubt it's mine," but moderator Wolf Blitzer pointed out that Romney, at the ad's conclusion, says he approved the message.
The debate was the 19th since the race for the Republican nomination began last year, and came five days before the Florida primary. Opinion polls make the race a close one, showing a slight advantage for Romney, with two other contenders, former Sen. Rick Santorum of Pennsylvania and Texas Rep. Ron Paul far behind.
Paul has already made clear his intention to skip Florida in favor of smaller, less-expensive states. And Santorum, who had been campaigning aggressively here, conceded Thursday that he's better off sitting at his own kitchen table Saturday doing his taxes instead of campaigning in a state where he simply can't keep up with the GOP front-runners.
Outside advisers are urging him to pack up in Florida completely and not spend another minute in a state where he is cruising toward a loss.
The cash-strapped Santorum seemed to be listening. He'll make a handful of Florida campaign stops early in the day, but will finish Friday with his family in Pennsylvania, where he'll spend all day Saturday before returning to Florida.
Despite the shift, Santorum stood out at times Thursday night.
While the clashes between Gingrich and Romney dominated, Santorum drew applause when he called on the front-runners to stop attacking one another and "focus on the issues."
"Can we set aside that Newt was a member of Congress ... and that Mitt Romney is a wealthy guy?" he said in a tone of exasperation.
In the days since Romney's loss in South Carolina, he has tried to seize the initiative, playing the aggressor in the Tampa debate and assailing Gingrich in campaign speeches and a TV commercial. An outside group formed to support Romney has spent more than his own campaign's millions on ads, some of them designed to stop Gingrich's campaign momentum before it is too late to deny him the nomination.
With polls suggesting his South Carolina surge is stalling, Gingrich unleashed a particularly strong attack earlier in the day, much as he lashed out in Iowa when he rose in the polls, only to be knocked back by an onslaught of ads he was unable to counter effectively.
But he struggled to find an effective attack in the debate and was more often on the defensive.
Romney pounced when the topic turned to Gingrich's proposal for a permanent American colony on the moon — an issue of particular interest to engineers and others who live on Florida's famed Space Coast.
A career businessman before he became a politician, Romney said: "If I had a business executive come to me and say I want to spend a few hundred billion dollars to put a colony on the moon, I'd say, 'You're fired.'"
Gingrich tried to raise questions about Romney's wealth and his investments. "I don't know of any American president who's had a Swiss bank account," Gingrich said.
Romney replied that his investments were in a blind trust over which he had no control. "There's nothing wrong with that," declared Romney, who has estimated his wealth at as much as $250 million.
Earlier Thursday, it was disclosed that Romney and his wife, Ann Romney, failed to list an unknown amount of investment income from a variety of sources including a Swiss bank account on financial disclosure forms filed last year. His campaign said it was working to correct the omissions.
Gingrich also failed to report income from his 2010 tax return on his financial disclosure. The former Georgia congressman will amend his disclosure to show $252,500 in salary from one of his businesses, spokesman R.C. Hammond said.
