Yeah, California is an interesting case. It is so bad here that only the most compulsive Democrat bootlickers are still behind a State administration that has probably broken all records for how quickly a political regime can trash a state. When the Democrats make epic messes of things they do control at the same time that the Republicans are gaining an increasing amount of control everywhere else, it is a setup for a landslide.
The bottom line is that the number of nominal Democrats who can stomach the Democratic party is shrinking. They may not be immensely fond of Bush, but the Democrats are so bad that it is almost a vote against the Democrats. It isn't that the Republicans are so good (though Dubya is lefty enough that moderate Democrats can deal with him), but that the Democrats are actually that bad. But we still have quite a way until election time.
You really think Bush will win Taxachusetts?
