My point is... a lot of non-leftist folks are "stuck" in these leftist-run areas. Economically stuck, and moreso now than ever.
50 years ago while in high school I chose a promising career, electronics. 42 years ago I decided to move to Silicon Valley instead of the Boston or Houston areas because my aging parents lived just 120 miles or so from the San Jose area. Now, decades later, we're on the edge of SF-Oakland-Berserkeley-Crazy, a degree of crazy that was not foreseeable as recently 5 or 10 years ago, let alone 50 years ago when I chose my career path. So, yeah, 42 years of my life - home, family, church, doctors and dentists, etc. - is here. A time may come when we will move elsewhere, but right now I'd rather see this area turned around, away from the crazy. In my low-key way I contribute things that contribute to such a turn-around.
Writing off whole states because of its crazies - CA, NY, WA, MA, IL, OR ... where does the list end ... or more to the point, where does this list of written-off states become dominant over the whole nation - is the path to the whole nation being turned crazy.
"Colorado" was Ayn Rand's place of refuge in "Atlas", too remote for an inept government to affect. Fiction writers create their own worlds to suit the purpose of their book. But in the real world of the US, there are no safe long-term refuges, and the more communities and states written off, surrendered to the crazies, the tighter and stronger the noose that will strangle the places of what will prove to be temporary and brief refuge.
