Sanders is a patsy in this election. Nobody else wanted to take on the anointed Hillary and her cash and FBI files. Bernie was a logical choice to make a coronation campaign appear competitive. The DNC didn’t foresee the number of hardcore communists in their party, and Bernie’s ability to connect with these parasites.
If the Bernie faithful figure out they have been played like fools, there will be a revolt. Hillary is counting on them to be too stupid to figure this out, which is likely the case.
Except if Hillary names Sanders as her VP.
In fact, O may have reserved the right to do so as a term of his agreement to pardon her after the election.
In that event, even if many of the pi$$ed-off R voters showed up at the polls the D's could easily have the popular vote.
