Donna Brazile: Dems ‘Worried’ About Enthusiasm with the Base

BRAZILE: "Democrats are worried about the enthusiasm. They are worried about making sure they can energize their voters. There is no question that we need to focus on the fall election, but right now, today, is a big day for Hillary Clinton. She has to bang on the fact that a quarter of the delegates will be people of color. Beyond that can she break into stronghold in the north east, Massachusetts, that's the key today for her."
