at least with la and sf it's also masses of liberal red state natives flocking there after college for tech/entertainment jobs or just because they want to be surrounded by their own kind. as somebody who grew up in la there's a huge divide between white la natives and transplants and the transplants are usually the ones who live stereotypical la lifestyles and have the stereotypical attitudes while locals just keep their heads down and try to survive and are conservative more often than not because we've had to grow up watching leftism fail over and over again.
