Many folks are familiar with ex-Californians changing the political climates in places like CO, WA and OR. And to a noticeable extent MT now. People who migrate to "better" places, but decide that their new home needs to change to be more like their old home and when enough of them arrive the vote turns left (or farther left in the case of WA and OR).
That's among the reasons I left NC 10 years ago. 1980's NC was awesome, by 2000 it had changed. It was hard to find a Country music radio station on the dial any more. Too many NY Yankees hats, not enough Wrangler shirts. Here in DFW we're down to 2 or 3 Country stations, depending on the reception where you live. I take that as a BAAAAD sign. When the Country music is gone, it's time to move on.
BUT...... It seems for now that the folks I'm meeting from CA are here for the right reasons. Texas has a "reputation". Californians of the more liberal mindset seem to be avoiding us. I haven't run into many hard-lefties. The few I've run into have been forced to reconsider or be marginalized. Lots more Midwest folks moving here than West Coasters. We've got Iowans by the trainload. We've got one Sprouts supermarket close enough to be useful, but I couldn't tell you where the nearest Whole Foods is, I assume there's some nearby. Hopefully that luck holds until I retire.
ETA: I looked it up. 18 miles to the nearest Whole Foods. I'm still safe.
