New York has the biggest migration out in the country. It has to take in immigrants to keep its population from collapsing. California was libertarian with plenty of Republican governors and mayors just a few decades ago.

I moved here when we had 2 Republican Governors in a row. So Cal (orange county and san diego) were a republican strong holds filled with war veterans and very little traffic or crime. It was fantastic. My friends would tell us stories of how it was even better when Reagan was Governor. (true story... they loved the 70s out here.)
