I don’t think the Rs can stop Trump. It would take a health issue or something like that.
Biden - different story. Is there a world in which the D party brokers basically tell him he’s not running and that if he fights them they will break out whatever skeletons they might have on him and his family? I can buy that theory as not being totally far fetched. But then you still need to get Harris out of the way and whatever comes with that. I know some speculate this is going to happen but publicly everyone is still rallying around the guy it seems.
