Florida is not part of the south. It is an extension of New York. The “natives” have been overtaken by northern retirees.
slight correction, up here in N FL we are still the old south, you might want to refer to the middle and south as the Yankee land.
Newt took the north , Romney took the middle and south where all the yankess are.
Santorum took, well just votes and they took them away from Newt thus helping Romney
I be a Southerner and no one I knew growing up in Alabama ever thought of Florida as a Southern state. We always, even then, 1950s and 1960s, considered it, as you noted, a Yankee retirement outpost.
