Although Joe Biden has currently declared he will not seek a run for the Presidency at this time, I believe there is ample opportunity for that decision to change.  If the FBI indicts Hillary Clinton on this email scandal, she will be precluded from running for office.  This is a Constitutional mandate.  Should this transpire, Joe jumps in, with Valerie Jarrett as his running mate, all the while spearheaded by Obama.  There is no love-loss between Jarrett and HRC, and this will further heighten the opportunity for Obama to effectively have a 3rd term as President.  He will most certainly be pulling the strings.  It further enhances their Democrats march as extremely liberal offering up the 1st female VP and black as caveat.
