Texas won't go Democratic this year, but by the end of the decade that's very possible if the Republicans don't take their minority problem seriously.
Now, I heard a very interesting analysis this morning. Californians are leaving California in droves and going to Texas. That is a fact. While taxes and government policies are part of the reason, the political climate is the biggest reason cited. Conservatives here hate what they have to live with. Ergo, these are mostly conservatives going to Texas.
If millions of conservatives are going to Texas, how does that affect your theory?
