You know, a buddy of mine is running for office in WA and he's in a close battle. I've been watching for updates there too. The Secretary of State's webiste hasn't updated the tally since 11:30 pm last night. If I remember from the close gov race a few years ago, they release counts in batches. I'd think we'd be getting an updated count soon.
Also, ballots in WA are good if they are stamped by the post office on election day (they don't have to be received by election day like in Oregon.) So, WA is always going to lag a bit.
