Do they have early voting in WA?
Several years back they made it ALL mail in ballots. The ballots have been out for at least a week now, so you can mark them and mail them in up to May 24th.
I think they vote by mail like Oregon. They send out ballots someone marks them and signs the envelope an they are dropped into a ballot box located in convenient places then they are transported to a counting place known by ????? to be counted by ????? and results reported by ????? Much like Chicago Circa 1909.
