I would just LOVE to see Biden get the dem nomination! The comedic gift bestowed upon us by his running would be legendary! Also, there wouldn’t be a chance in hell he could win.(I don’t THINK - ....you just never know anymore)
O he could absolutely be President. Obama could pull a Putin/Medvedyev switch and hint that he would be a key advisor/cabinet official or newly appointed Czar of America and Biden would rack up 300 electoral votes.
