I had advised people to write in all candidates where possible for a reason. That leaves a paper trail and poll workers can witness that. Do the same thing as 2020. Get the same result.
That is throwing your vote away. When you check the "write-in" box, your vote automatically doesn't get counted and must be hand-adjudicated. And unless there are enough write-in ballots to sway the election, they don't even bother.
