You gotta remember though, Arnold is a California Republican. Just like some people are pissed off at Scott Brown in MA. He's a Mass Republican which means he's much more liberal than you or I would like. But he is soooo much better than Kennedy. Same for Arnold, yeah he's pretty liberal and he's done some bad stuff but he has also done things that no Democrat would have ever done.

Multi party systems don't work well. Look at Europe.
