Florida hasn’t been Deep South for many decades. It can be lumped with beltway VA and most recently North Carolina as contaminated by migrant liberals.
North Florida & the Panhandle are still part of the South.
Miami? Well, back in 1986 they were saying “Would the last American leaving Miami please bring the flag?”
Heck, Okeefenokee & the Seminoles who live there are more Southern than snowbird land.
The original Northern transplants to Florida were the first people in the state to vote Republican.
