Shortly after the convention Hillary will drop out do to health problems. Obama will pardon Hillary for whatever wrong doing she is being investigated for. Hillarys running mate, Biden will go to the top of the ticket. Biden will recruit Warren to be his running mate.A plausible scenario, for sure. Obama simply doesn't want the Clinton's back in the White House, and he's in complete control.
Dems still lose to Trump. Positive vision versus continued division. Landslide.
