Lotsa folks dislike Trump including many who voted for him. They justify it by saying "Hillary would have been worse". How they KNOW?

I don't know abiut "worse", but she almost certainly would have been "bad" while Trump was an unknown factor at the time - and got his vote out, a "yuge" percentage of the electorate didn't take him seriously, thought Hill was a slam dunk so didn't bother to show up and vote. Apathy got Trump elected.
