I'm not so sure.
A possible scenario:
The Odumbo's hate the Clinton's. I don't think Odumbo wants Hillary to be elected.
So what's going on?
Obviously, Odumbo is protecting Hillary right now. Why would he do that if he hates her?
Suppose Hillary's campaigning is allowed to continue on until the eleventh hour before it implodes.
Only Bernie Sanders remains. We know that isn't going to be allowed.
The Democratic Convention is September 3rd, 2016.
Hillary is drummed out, and Biden steps in at the last minute and all the delegates throw their votes to him.
Biden, with running mate Elizabeth Warren, has avoided having to show up for any debates, spend any money - essentially having to do no campaigning at all.
Think about it...
