It was so close I doubt finding the real winner is possible.
Hopefully, riots will erupt through out the state and Civil War will break out in Washington. After a while, the state will be split in two. Eastern Washington joins Idaho and Western Washington changes its name to something cool. Maybe we can take Portland too, and give Eastern Oregon to Idaho as well. And then, when America takes over Canada, we can take Vancouver and Victoria. 
You are correct that it is hard to know who really won. We can do a second manual recount and get Rossi the winner.
He should get the office for winning two out of three counts though.
It would be interesting to see what happens if the Republicans try to swear ROssi in as Governor.
It would also be interesting to see hwo a revote in a month would go.
That is probably unlikely; another manual recount would be unlikely to change the count by more than 100.
Your second idea is interesting, but unfortunately is sort of against state law, which considers a manual recount the final, last-ditch count, or something of that sort.
If Republicans try to swear in Rossi, they will be summarily ignored and probably made fun of. But it would be in character for a stupid election season.
Hard to say who would win a revote.
