Seattle is a hard core leftist city, but the rest of the state leans right. I'd say that as a whole the state leans left with about 55% liberal and 45% conservative. The middle is pretty squishy though and conservatives manage to win from time to time.
In the primary last week, democrats out voted republicans 60-39 with 1% libertarian.
Oh, did I mention that it rains here all the time?
