I wouldn't be too surprised to see Santorum win a couple of Panhandle counties, and I also imagine Romney will win a few random counties up there due to a Santorum/Gingrich vote split. Romney definitely carries Leon County, too- BRTD has that right, though I'd put the margin as >40% unless Ron Paul has a really good showing from FSU (I wouldn't be surprised).
Romney certainly carries the Jacksonville area again, and he'll probably do pretty well throughout much of the I-4 corridor. Gingrich certainly wins Miami, though, if PPP's racial crosstabs are accurate.
I think Mason-Dixon had different results for the Cubans, but I can't remember for sure, so many polls, so short a time.
PPP has consistently had Gingrich winning Cubans with 40%+ of the vote.
