Not to be picky, but "snowbirds" are people who have residency in another state (usually in the NE or Mid-Atlantic states-many actually from Canada) and only live in Florida in the winter. They aren't residents of Florida in terms of voting.
The problem is the liberal people from NE and Mid-Atlantic states who move to Florida permanently. Rush talks about this quite often. He terms Palm Beach "New York City South".
As I understand it, the eastern coastal areas of Florida are heavily Democrat, but the western coastal areas and the panhandle lean conservative. Maybe a Florida resident can more fully explain the break down.
Tell me about it. Until recently I lived in Seminole County, FL, where Democrats are already a third party. There a typical local election pits a Republican vs. an independent, or a Republican vs. a Libertarian. Now I'm in Lexington, KY, which is apparently a more liberal community, judging by how many folks expect the government to look after them. They didn't even have a Republican candidate running in last year's congressional election! No doubt it's the influence of the University of Kentucky, which owns a big chunk of the city. I hope the demographics also work the other way, so I can bring my "redder" state values to a state that's supposed to be "red" already.
