California is a strange thing. It used to be traditionally Republican and then blinked red-blue-red through the terms of LBJ, JFK and Nixon. Coupled with the state's crippling financial woes is a general feeling that Obama didn't do what he said he would do. I don't think that there's been this much vitriol flying about since the days of Carter.
The biggest issues of this campaign will be unemployment and the national debt, which less than 4 hours ago (at time of posting this), hit $16 trillion.

If you look at a county by county map, California aint as blue as first thought. I'm trying to find a booth-by-booth set of stats, but I bet that the GOP will be campaining harder for turnout than the Democrats will. Admittedly the only polls which matter are on Nov 6 and Dec 17, even so, the last serious statewide poll was done almost 2 months ago.
