Its possible that the GOP can pick up Oregon sometime, They'd just have to work very hard (See Indiana) as for Washington, I think that's a bit of stretch right now. California will have to see some major revelations in the next few decades to vote Republican. Perhaps if we get a good strong Republican governor elected in 2010 who becomes extremely popular with latinos and independents it can be done one day, but the GOP will have quite some work to do before it happens.
…Which means a change in the Republican Party's platform.
Big changes!
