It's becoming Californiaized, there is also a lot of tech bros moving to Denver. A similar thing is happening in Texas. There is lots of ski resorts and outdoor recreation, which brings in lots of eco friendly types.
You’re right, but there are counter trends in Texas that seem to be favoring Republicans much more (Conservatives from CA moving in as well and not just techbros, Hispanic trends especially in the RGV, Houston and maybe SA potentially being maxed out for Dems.)
Eh "much more" is probably stretching it. Especially the RGV trends (Which mean little in the overall vote count), how it ain't just CA Conservatives moving to Texas & basing Hispanic trends off of one election.
It'd be one thing if Trump won it by 7-10%. But despite all the "GOP favored" counter trends you listed, it still swung nearly 3.5% to the left.
