Heilemann: The Only One Who Likes the Polls Better than Donald Trump Is Bernie Sanders

HEILEMANN: "She never had crowds like Sanders has. And the sense of slippage that’s happening around Hillary Clinton even though, again, she’s almost certain to be the Democratic nominee -- you know Bernie Sanders loves polls that show her not competing well against Donald Trump. The only one that likes those polls better than Donald Trump is Bernie Sanders. It keeps energizing and it keeps him continuing onto the end, and strengthens his hand. And when he gets to that convention this summer."
