Sure, there have been loads of polls today. This one, a robo-poll of 831 Republicans, carries a little more weight because it's conducted by Randy Nielsen of Public Concepts in West Palm Beach and Pat Bainter of Data Targeting in Gainesville.
Between the two of them, they're probably responsible for helping elect or advise nearly every major Republican in the Legislature. Both are Republican Party of Florida consultants. The results:
Mitt Romney: 40%
Newt Gingrich: 30%
Rick Santorum: 16%
Ron Paul: 8%
Nielsen said an intriguing aspect of the poll are the regional breakdowns. Note the North Florida numbers, which help show why Romney spent a little more time there recently.
North/Panhandle: Gingrich (35), Romney (27)
Orlando/Space Coast: Gingrich (30), Romney (44)
South: Gingrich (28), Romney (44)
Tampa Bay: Gingrich (31), Romney (38)
For those who care, South Florida is outside the error margin for the regional subsample.
