Texas is still fairly conservative, but Austin, Dallas, and Houston are lost forever. I think Austin could be "Paris" west. Instead of the peso for pizza, it might be the Euro. In Houston, you can drive for miles and never see an English sign other than road signs. It's either Vietnamese or Spanish. They are all Dems.
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.
