California is not quite as blue as it “votes.” They were among the first victims of organized Democrat election fraud.
I don't know about that. In my neck of the woods there were celebrations in the street, complete with fireworks and shouts of "Freedom!" and "F--- Donald Trump!" on November 7 after the media announced Biden's win. Needless to say, I don't advertise my political views.
It appears that Californians are migrating to other western states, with bad results for those states, AND California is getting more liberal due to the voters who replace them.
A look at the D increase in both branches of the legislature over time shows this.
