Bad poll. Biden received nearly 60% of the WA vote in 2020 but among the poll respondents only 45% say they voted for him. So this poll skews very heavily Republican. Garbage needs to be tossed out.
Unfortunately, you are 100% correct. There is no chance that Trump will carry the state. We are all mail in ballots so Democrats control the vote counting. Even if he wins, King county will start finding boxes of uncounted ballots like they did with Christine Gregoire in the 2004 governor's race.
