Austin is as blue as they come (and way less of the neoliberalism you see in SV). Houston from what I can tell has become much more liberal too (partly because a large influx of Katrina refugees).
Hot take - with all of the migration to Texas, this state will be blue in the next 10 years.
The only "conservative" things you find in those areas is (1) big trucks (2) guns (3) tobacco (4) sports. Not much different than what you might see in rural CA.
