The last gasp of the 'mind your own business' conservatives in Texas was either the 2016 election or the one after that. There was a period of time where you had the Lt Governor trying to pass culture war bills (like anti-trans bathroom bills) in the senate and then they would die in the house when the speaker wouldn't put them up for a vote due to it being bad for attracting businesses. Once the MAGA Republicans got voted in, it's been full steam ahead for them.
It's not like things were great before then, but it wasn't this race to the bottom like it is now.
It's hard to imagine police officers not backing their boy.
