https://www.cnn.com/election/2018/exit-polls/texas/senate How long have you lived in Texas? Born in Texas (58%) O: 51% C: 48% Moved to Texas (42%) O: 42% C: 57%
So people move to Texas to be even more awful. That would explain a lot. Bit like the pilgrims, they were not running away from opression, they wanted to oppress more than was allowed in England.
Have lived in TX since birth, seems strange to me. Only anecdotal but the people I grew up with seem a lot more conservative than the people I have met that have relocated.
