Up until recently Dallas / Ft. Worth and Miami where conservative. The Cubans that fled communism held Miami as a conservative metro up until about 15-20 years ago. Orlando and Tampa where the same. Orlando for different reasons but Tampa was largely due to the conservative Cubans as well.
Texas and Florida are two of the states that are experiencing meteoric growth and to imply that those moving in are not shifting the political climate to that in which they came from is to ignore the fact that both went from solidly conservative states, with conservative large metros. To toss up states where the metros became in flux. To ignore that those moving in are not voting in the same failed policies that they are fleeing ignores the fact that both states policies are in fact starting to trend towards taxation, lowering of property rights and large scale social programs. The spade is a spade.
The same happened to Denver over the past 20 or so year.
On a note related to the main topic, I live in FL in the Florida Keys, it is a paradise I spearfish on the weekends and am usually out on a boat. Prices have gone up here, but one can still purchase a home on the water for under 500k. I could barely get a decent apartment in the valley for what I paid for my 7 acres of oceanfront land and home. I mention this to make the point that I can certainly see the draw, you get so much more for your money if one sells out of a major CA metro and moves to one of the growth states.
