Trump is an amoral, repugnant leader who will further divide this country. It's what he does. He pits groups against each other. It's not melodramatic to say that the republic may not survive 4 more years w/ him in office, at least as it's currently constructed.
I haven't voted for either major party since 2008. My conscience is clear. I won't make the kinds of compromises that are required to settle on either major candidate in most elections.
Not that I wouldn't vote for either party again. Kasich was the last candidate I liked on the R side, and Klobuchar was the last one on the D side. Of course, neither had a chance.
Every voter needs to set the bar higher. Voting has become a kind of eff you to all of the people we disagree with. We need better leadership. A Trump/Biden race is really a catastrophe for America.
