White CA voters have tended to be less religious for a long time, while also being more into self expression. It's socially anomic atmosphere, and materialistic (even hedonistic) culture in many places (think LA and Orange County in particular), tends to cause things to go that way. Combine that with the white working class leaving, the labor-management divide waning away to next to nothing (that drove many socially liberal minded executive types into the Pub party), and the industrial base being more knowledge based, with aerospace going away largely, and the Hispanic percentage steadily increasing, and now the Asian (who don't take too well in general to the vibe of Evangelical Christianity), and you have a recipe for Pub disaster.
Interesting. Sounds like a response to some of the structural deficiencies of the modern GOP.
I went over some of the GOP's California CDs, and 39th looks like it has some potential, 36th has a R+1 PVI but a Democratic Rep and its voting history does suggest it's likely to be more Democratic than not until 2022. Given the demographics of the 25th district (assuming Wiki is right) and past election results, this is a flip just waiting to happen. 21st is a Republican-held Democratic-leaning seat, so incumbency is their savior there I guess. The 10th district is yet another one on a knife's edge
45th also looks like it has some future potential, but not before the next redistricting and who knows what it will be then.
I'm actually quite surprised how precarious the situation is with their remaining seats in this state. I thought they had already basically hit rock bottom, but obviously there is a ways to go yet.
