Biden. Definitely the preferred candidate of the Obama/Clinton wing. After that, maybe Cory Booker. Although I can't imagine that the DNC will dare allow superdelegates override the voters if they reject Biden. That might split the party even more than it was in 2016.
Trump has "questionable behavior of touching women and little girls" and look how well it worked for him. Seems Biden would be a good candidate to go against Trump in 2020.
Um, Trump literally had (still has?) a lawsuit against him in raping a 13yo girl at a high-roller party by the now adult woman. Then the other 17-18 accusations of sexual misconduct levied against him over the course of 20ish years. Then he bragged about being able to do it.
Do you just ignore this when trying to paint other politicians as molesters, or do you just not care?
I don't want Biden to run though, his time came and went. We need new blood.
