Demorats do have options though....they could pull him out for a number of reasons. Which would open a whole can of worms....hello Bernie?
I really don’t know who they could replace Joe with.
If Bernie, there’s a lot of Hillary voters that won’t vote for him.
If Hillary, there’s a lot of Sander’s voters who won’t vote for her.
I don’t seen anyone in the primaries that could unify the whole democrat base.
They would have to go for a new name.
