I'd wager most of the people fleeing California now weren't born there.
One of the things I point out to others here in California, is that San Francisco used to be Republican. Then it got invaded by outsiders in the 1960's who brought liberal beliefs from elsewhere. I was born and raised in San Francisco, very few natives remain. SF had an unbroken line of Republican mayors almost from the 1906 earthquake to the mid-1960's. used to be decent, now it's crap. The coastal cities got taken over by libs. One daughter relocated to Texas, also born in SF, she's not a lib.
Maybe, but a lot of us native Californios have pulled up stakes and moved on. I've been in Texas for seven years now.
