I can’t remember where the poll is, but I saw a breakdown of that vote by recent moves to Texas vs. established Texans (5+ years), and 57% of the recent moves voted for Abbott, and 52% of established Texans voted for Beto. Coupled with the Republican voters in Texas, it was more than enough to swing that election (plus, turnout was abysmal at, like, 24% overall, iirc).
Now, a sizeable number of those recent moves came from rural California. Texas was their Conservative dystopia they wanted to live in; but notice I said “was.” Florida has become the new dystopia for Conservatives, so I think Texas Republicans’ days are numbered if they keep on this anti-bodily-autonony kick.
