It depends who the Democrats nominate. Right now, their candidate field is packed with people who have endorsed ideas that border on Looney Tunes. I don't want a second Trump term, but if the D's nominate a nutball, well, I have 2+ years of evidence of what a Trump presidency looks like, and while I don't love it, it's not the disaster I feared in 2016.
So I'd rather have 4 more Trump years than any years of Warren or Sanders or Harris or Booker. But if the D's nominate someone sensible like a Biden or Klobuchar or Hickelooper, I'll vote Democrat.
