Just about any way you crack it up, this should mean one more republican Congressman for Oregon. Though looking at the present state of politics in Oregon combined with an utterly incompetent country club state GOP, odds are they could lose the new "sure thing" congressional district as well.
A tenth WA district would probably be Republican, too. It would ruin the perfect East-West balance in districts we've had for a while, meaning the tenth district would have to have large portions of both Western and Eastern Washington. The most logical place for a district to crossover would be in the southernmost part of the state, containing parts of suburban Portland (Vancouver area) and into South Central Washington to the Yakima area. I would expect the GOP to have the advantage here, but, as you point out, the GOP in the NW is in a pretty sorry state as of late, so who knows (WA-3 is a lean R district that voted for Bush in SW Washington that is held by a Democrat who has been easily winning re-election). I doubt the GOP will be able to keep WA-8 too much longer, especially if a tenth district is added (changing the rest of the districts significantly). With 10 districts in Washington, 7 held by Democrats and 3 by Republicans seems the most likely.
