I think the idea that California out migrants ruin neighboring states is over played. Many of these migrants are conservative and want out for that reason.
Don’t count out Colorado, yet. Colorado is more like Iowa, it can change party back and forth. Eventually Colorado voters will get religion on what their taxes are buying.
No one wants to live in Wyoming which is not that different typography and climate compared to Colorado or Utah. At least it has reliable representation.
The table shows Wyo. had a significant domestic outflow.
Not so with Montana.
I hear that again and again. Conservative Californians who truly do feel happy at leaving. But soon they relax and start voting for some odd things.
I don’t see them going places and assimilating to the local culture.
