Also, why are Democrats doing better in Oregon than they are in Washington state?
In WA Republicans have been lucky / Democrats unlucky in several Obama voting areas (LD-41 is D+10, yet has elected a Republican in both 2010 and 2012), especially in the suburbs of Seattle to the East, SouthEast, and around Tacoma/Pierce County. Some excellent candidates this time around with Tom Steyer money didn't seem to make it through. I remember in 2010 when so many Democrats in swingy suburban districts lost seats, and this time the GOP dominated against some fairly strong candidates. Democrats do have a lot of fodder against them for mismanaging the budget under Gregoire, but not sure why they can't seem to win any of the fairly easy Eastside districts, and have completely lost a hold of more exurban King/Pierce/Kitsap county districts. Unfortunately most of the vulnerable districts are not up for election again until 2018.
