Way too much enmity between the two of them for any pairing to occur. If it did happen, it would be the biggest political axe-burying in the past century.
Incorrect because Barrack can be forced to take the vice presidency to unify the party
Democrats will tell him he must do it or we lose black voters plus you are a young man who has plenty of time to be president. In fact you are next in line because you will be VP
But Hillary being older than Barrack and kicking around politics a lot longer would not run as Barrack's VP. Too humiliating plus no upward lift to the ticket.
But a Barrack VP would lift up a Hillary ticket. Imagine him out campaigning!
