A dramatic swing in the Florida polls has shifted the momentum yet again in favor of Republican presidential candidate Mitt Romney.
The former Massachusetts governor now holds a double-digit lead in the pre-primary polls.
The Sunshine State's primary will be held Tuesday, and former House Speaker Newt Gingrich, R-Ga., has been blitzing the state with television commercials and campaign appearances trying to catch up.
With less than 24 hours of campaigning left before the primary, the latest polls suggest Romney could be on the verge of a big win.
The American Research Group poll projects Romney capturing 43 percent of the vote versus Gingrich's 32 percent.
Gingrich blames the shift on Romney's "money power" and negative campaigning.
"I have an opponent who has money power, and we need people power to offset money power," he said.
Over the weekend, Romney's campaign launched a new round of attack ads against Gingrich.
Romney has spent more than $13 million on negative television commercials since the South Carolina primary. Now, even as his lead deepens, he isn't letting up his attacks.
"Speaker Gingrich, I think, has painfully revealed himself over these last few days and it's sad to watch. I think unfortunately we're seeing some of the qualities that got him into so much trouble when he was Speaker of the House," Romney said.
Gingrich received some much needed support from former presidential candidate Herman Cain, who announced his endorsement over the weekend.
Meanwhile, former Sen. Rick Santorum, R-Pa., cancelled all of his Florida appearances to be with his daughter Bella, who has been hospitalized with pneumonia. The 3-year-old suffers from a rare genetic disorder called Trisomy 18.
Santorum said his daughter's health is improving.
