tech workforce is generally liberal or are at least centrist moderate. Texas is not an ideal home for most of them.
That stereotype is about a decade out of date.
Texas is very much like New York, California, Washington, Nevada, Oregon, and most other American states: Blue large cities surrounded by red elsewhere.
The list was examples, and not exhaustive. It's also true in Arizona, Ohio, Wisconsin, Minnesota, Illinois, and probably a bunch of other states that I'm less familiar with.
My point stands, though. The Texas thing is still a stereotype, and still at least a decade out of date.
