@georgeob1,
Victor Hanson wrote a very interesting and enlightening article in National Review about this Californian fact. Highly recommend it. Apparently Hanson has long family ties to the State (and rural area) and is loath to leave what he describes as a society rotting from within. Can't imagine he will endure for much longer.
I have family in California: A retired college professor brother with a Phd in Economics, his daughter a partner in a law firm that specializes in Hollywood Celeb clients, and his son, a doctor. All of them are liberals, however their left-wing zeal diminishes in the order I've listed them.
I love them all but my brother and niece came dangerously close to damaging our relationships after the election. Thankfully they came to their senses after a few playdoh sessions and all is OK (Unless they are members here and identify me by my referencing them

).
The "kids" live on the coast and my brother lives in Palm Springs for half of the year. All of them adore California and except for a few complaints about high costs of living (which they all can overcome) they wouldn't change their beloved State much at all.
Their thinking about politics and by extension California, could not be more different than my own. Since I too was afflicted with liberal thought until the age of 30, I believe I know how they have come to think as they do, but obviously they are not willing to accept my explanations for the positions they hold. Every once in a while I see signs from my nephew that he is evolving, but he lives in such an Echo Chamber that I'm sure it's difficult for him.
What is heartening is that despite our polar opposite views on issues that a lot of people would describe as very important, we still have very caring relationships and can easily manage to spend time with one another that doesn't involve political discussions.
Still I would very happily visit them all in another country if California were to secede.
For quite some time it has been conventional wisdom that things happen in California and then spread East. To some extent this has been true, but its unlikely that the States to California's East (especially those that have attracted disaffected Californians) are going to embrace the suicidal policies of the Golden State.
