All votes in Washington State are mail-in ballots. Would be easy for a few postal employees to swing an election.
16 years ago I lived in Oregon. it is a mail in ballot state also. I never got my ballot and was not able to vote in that election. when I figured out that I did not have a ballot I couldn’t even pick up one because all ballots are mailed out to the residence. I am positive that I never got mine because I am registered as a republican. it is the only presidential election I ever missed voting in
Oregon too, I take it personally to the court house and give it to the County Clerk.
