It is not going to be Joe, they will slip either Hillary and Micheal in at the last moment or Micheal and Hillary.
As usual they will cheat.
I agree. Joe is a straw man. He’ll either be taken out and replaced (as you point out) or he will be given Hillary as his VP. His life isn’t worth squat at that point. With Joe in dementia care or dead, Hillary will finally get her shot at being Dictator for Life.
