"Bear in mind that nobody knew Sanders before this debate."Now, for the first time, they're seeing him and seeing that he's not some guy out of a nursing home. He's got charisma and even a sense of humor about him."That's going to buoy him — and you're going to see that roughly 15-point gap in the national polls that Hillary has closing fairly sharply."
