Biden will NOT be the nominee. ZERO percent chance Mr Senile will be picked by the liberal nutcase voters, which are an ever increasing segment of the Democommie Party.
Abrams is a loser, and has a loser mindset. If they pick her, she does not help the ticket. And the mention of Sally Yates, a no name bureaucrat, get real. And the other two are virtual unknowns too! No, he needs someone with noted recognition, and someone that represents the fringe, so Biden calls on Warren, and perhaps Clinton.
Imagine Clinton getting the nod, and some months after the election, what could happen to Biden....hmmm.
I hope it is Warren, but she is such a nutcase, I just do not see her getting there. And then Biden, he is without doubt a blatant crook.
I still think Clinton comes to the rescue, perhaps at the convention. And they are just dumb enough to select Michelle Obama. And then there is Oprah. She runs she could easily win the nomination. The fact noted by Wikipedia, assuming it is still there, that she was a crack whore for two different guys, may hurt her, and it might help. Those with a serious drug past have to be a large demographic.
