This is very wrong. Drive the 5 sometime. Outside of LA/SF it gets very red, very fast. Even within those areas it's only the centers that are truly "blue"; (AFAIK) Orange County is particularly conservative, for example, and it's always been my impression that places like Marin, Palo Alto and Orinda are the same way. It's where the term "California Republican" came from.

Look how long it took to legalize gay marriage and weed!
