Clinton overperformed Obama in Texas, as even the article seems to cede obliquely. Where's the evidence this is systemic and not just a cherry-picked anecdote? And by the way, if it was systemic, what's the evidence it has anything to do with values and not just the obvious explanation that the people are wealthy and Texas has lower taxes and they're fleeing primarily for pocketbook reasons?
I have no doubt that there are individual people moving from everywhere to everywhere for every reason.
I know journalists feel bad that they missed the collapse and rage of white rural America, but they don't need to do a thousand of these pieces every week designed to make it very clear that Actually There Are Places Between The Coasts without saying anything of substance. Useless navelgazing.
