I hate to say it, but it sounds like the judge made the right decision: If he indeed didn't have the jurisdiction to order a new election, then to do so would have been the kind of judicial power-grab we despise. Sometimes you have to take the bitter with the sweet.
Also, as other posters said, this one was going to the state SC, period. It's far from over.
I agree that the judge made the right move. I don't believe that lower level judges are possessed of sufficient authority to order momentous changes. His ruling seems to be favorable to the Republicans, and stopped short of the revote due to concerns of overstepping bounds. We'll see how this plays out at the WA SC.
For some reason, and I know nothing about this court, I have high doubts that one could obtain justice from the WA State Supreme Court.
