It should be fairly easy for the Republican lawyers to challenge that the results from specific a precinct, surrounding Pullman would be Democrat, rather than Republican. It is also possible that students, who were registered in other counties, voted in Pullman on provisional ballots. I have heard it mentioned many times that a lot of the college students didn't even know that they had to vote in their home town.
I suspect MoveOn.org herded their student following to the university voting site. I would not be surprised to see those votes going overwhelmingly for Gregoire.
But it may be a moot issue. The votes were apparently verified later rather than before they were counted, hence they will likely be deemed proper and allowed to stand. That means they can't be proportionally assigned, hence the county versus precinct level assignment is unnecessary.
But then there are the purported felon vote offset in pro-Rossi counties.......Repubs better get crackin to check those out.
