I think we are looking at the same cluster as last time. Whoever the DNC picks will leave out a favored candidate. The Dem voters will vote Dem but not straight ticket. The division will hand the election to Trump. The Republicans have shown they will hold to the party and a sitting president will not be voted against in any measure that matters.
