For those in the Evergreen State I suspect getting the law overturned is a longshot. You will need a new governor (since Gregoire supports it), and many new legislators. The best chance--though still likely a difficult fight--is an initiative.
It would take a lot of signature (241,153) to get it on the ballot, but that's still probably the best way to get the law repealed.
As for Stars, the decision makes sense. I doubt that Stars fears a prosecution by state prosecutors; however, the combination of a valid state prohibition
and the UIGEA likely caused Stars' reaction.
The only long-term solution in the US is legislation. As the Engineer and Skall have said on numerous occasions, the status quo is unstable and will not last. For those who want to go back to the Party days of 2006, we can't. For those who want to have things stay the way they are, they won't.
