Hillary isn't really very charismatic. I liked Bill, he seems like a nice guy, a smart guy. Even if she had the same policies, which I don't know if she does, she just isn't really likable. Just like with his other main campaign points, racism and greed, he just has to keep pushing that point, because it seems like hate for the other side is better than actually having reasonable policies on positive change. He doesn't have any. Take from the poor, give to the rich, and borrow money for a never ending debt that results. That's his policies.
