Stop lumping everyone in neat little buckets

It's not like you can swoop in and take just Austin. But if you storm in and take all of Texas, you'll be overrun by the majority of fascists.

I would say you need to take the blue and perhaps the purple states, get them self-sufficient with proper healthcare, raise the quality of life up to par, fix education, the judicial system, and elder care. The blue cities within the red states will gladly immigrate, leaving behind a broken and desolated hellscape in their wake that the rural residents wouldn't touch. Taxes will go through the roof with population drain. The blue cities and suburbs will grow. You'll get more of the red to convert. Your own housing crisis will just evaporate.

If you try to eat the red shit-sandwhich whole, the red will just add to your own red and we'll be drinking our poison from the same vine.
