The danger for Trump is that Obama will invoke Plan B: Remove the Superdelegate support for Hillary in which case she cannot win the nomination and hand it to Bernie or Biden or Biden/Bernie.
Before everyone gets too giddy, keep in mind that the Republicans are unifying. The Bernie/Hillary camps have not. That will happen at some point and we will most likely have a very competitive race in the Fall.
Get ready to fight tooth and nail to reverse the damage that Obama and his cronies have done the past 8 years and Make America Great Again! Take NOTHING for granted.
