Florida Primary

Newt Gingrich sharpened his attacks on Republican rival Mitt Romney on Sunday. A new poll shows Romney leading the former House speaker just days ahead of Tuesday's presidential primary in Florida.

The former House speaker is trying to cut into the resurgent front-runner's lead before Tuesday's primary in the Sunshine State. Newt Gingrich accused the former Massachusetts governor of "carpet-bombing" his record. Mitt Romney meanwhile shifted his focus back to President Obama's record.

Former House Speaker Newt Gingrich made appearances before two communities in Florida Friday whose votes he hopes to win in next Tuesday's GOP primary. He spoke to Latino home builders and business people in the morning, and had a rally with a group of Republican Jewish voters in the afternoon. NPR's Brian Naylor reports.

Republican candidates' efforts to win Hispanic voters have intensified in advance of the Florida primary, airing ads in Spanish and contending over immigration. Host Scott Simon speaks with Maria Elena Salinas, co-host of Noticiero Univision, about Hispanic voters' role in the Republican primary and the upcoming presidential election.

After his second-place finish in the South Carolina primary, Mitt Romney arrived in Florida armed with money and organization. With three days until the primary, Romney's recent debate performances and an endorsement from Puerto Rico's governor are part of his campaign's growing momentum.

The answer: George Romney's parents were U.S. citizens, so at birth he also became a natural-born U.S. citizen. His son, Mitt Romney, brought up George Romney's birth during Thursday's Republican presidential debate to rebut the charge that he's "anti-immigrant."

From his assault on food stamps to his eviscerating of the news media, Newt Gingrich literally brought crowds to their feet during last week's debates in South Carolina. For a moment, you could almost hear the rebel yell. But Florida has been a different matter.

Former Pennsylvania Sen. Rick Santorum, a Christian conservative who adamantly opposes legalized abortion and same-sex marriage, likely won't win Florida, and he's polling nationally at about 16 percent. But he could have a big impact on the GOP race in the Sunshine State and beyond.

Thousands of Florida Republicans have already cast their ballots for Tuesday's primary — through early or absentee voting. And that may be a problem for Newt Gingrich.

As the nomination process moves forward and the field of Republican candidates gets smaller and smaller, it is harder and harder to know just who is in the lead.
