I live in Washington and there is no electronic voting. We get mail-in paper ballots. I lived in Oregon at the turn of the century, and they also used mail in paper ballots.
So the only way they could change the vote is they hack the counting machines.
What they seem to be doing is requesting a ballot in somebody else’s name and voting for them.
“I live in Washington and there is no electronic voting.”
From the moment it is entered into a computer then your vote is subject to any form of digital manipulation. Even at the state level.
