PPP Florida poll: Newt 47%, Romney 17, Cain 15

You read that right -- 47%.

Public Policy Polling, which did the survey, gives "one of the key emerging trends in the Republican race -- Gingrich isn't just rising, Romney's also falling."

More from PPP: "The biggest reason for Newt Gingrich's rise is that he's picked up the voters of Herman Cain and Rick Perry as their campaigns have fallen apart. But these numbers make it pretty clear he's doing more than that- some of Mitt Romney's '25%' is starting to fall off and move toward Newt as well."

Newt leads among both tea partiers -- getting 53% of them, compared to 24% for Cain and just 7% for Romney.

But Newt also beats Romney among moderates -- 33-22%.

Newt's favorability is 72/21.

Gingrich is especially strong among older voters. "Republican primary electorates can skew pretty old so Gingrich's support on that front bodes very well moving forward," writes PPP. But that's not to say Newt only gets the support of older voters -- he wins every age group.

PPP also points out that Newt could still improve. That's because Cain could very easily drop further -- and since 45% of Cain's supporters say Newt is their second choice.

On the recent dust up on immigration: 57% support Newt's policy. 20% oppose.

Newt's favorability among men: 76-23. Women: 67-19. 48% of men support. 45% of women. Just a huge gap!
