A dark horse candidate like Trump was last year.
Somebody who can successfully corral SJWs, moderate democrats, and rust belt union workers behind a single banner.
Somebody who's very likeable and charismatic, preferably somebody who speaks like Trump and Sanders speak with a straight shooter demeanor.
I think you are exactly right in this regard
I've said before that "being able to talk like an actual human" is the biggest requirement for any 2020 candidate IMO.
Some people take this to mean "We need a Democrat with Trump's personality", which I think would be a mistake. I don't think that plays with the Dem base the way it does for Republicans.
-Have you ever heard of Joy Ann Reid, Kurt Eichenwald, and Sarah Kendzior?
