It’s simple for me. The man is entirely unfit to be President and therefore will never get my vote. He’s mentally unstable, extremely narcissistic, dishonest (I hated Bill Clinton’s dishonesty, but Trump is the most prolific liar ever elected President), dishonorable, uncivil, irrational, paranoid, too emotional, and an unpresidential cowardly bully.
I like some of his domestic policies, but think he sucks internationally. I don’t like anything he’s done enough to overlook the fact that he’s unfit.
If it takes electing Biden to purge him and Trumpism, so be it. Shame is the we could have nominated Haley and likely easily defeated Biden.
