Hilary's in meltdown mode, and Biden chooses NOW to call up warren to chat it up.
IMAGINE how the liberals /dems would unite quickly behind a one-term Biden presidency with Warren announcing an instant endorsement + Biden winks that he'll choose her as the VP choice?
It'd nullify the female factor (for which Trump may choose Fiorina, despite her zero political experience and what everyone agrees is a very weak run at HP)
