I’d rather not vote at all than vote for Trump.
Years ago, when I was a teen, I said something disparaging about the President at that time – most likely Carter. My father z”l heard me, and he said, “Look, if you don’t agree with something the President has done, that’s fine, but don’t disrespect the President or his office.”
That’s why I could never vote for Trump. He himself didn’t (and still doesn’t) respect the office. He is simply not a mensch.
(As an aside, I’ve been registered as a Republican since I first registered to vote when I was 17. That’s a long time ago. This past election was the first time I ever voted for a Democrat for President.)
