I would vote for Biden before Hillary.
Since I can't morally vote for Trump, I'm looking at either a Hillary vote or a throw-away protest vote. Still haven't decided...
If Biden were put in Hillary's place, I'd probably vote for him rather than a protest vote. I think a lot of never-trump republicans might be willing to do the same. The problem is the never-trumps are dwindling the closer we get to the election which was totally predictable.
