Charles Krauthammer said on "Special Report" tonight that new polls reveal Hillary Clinton's campaign could be in trouble.

"We've gotten to see her. And it turns out, the more you see her, the more her numbers go down," Krauthammer said. "That's the definition of a weak candidate."

He added that Democrats have a big problem, since Clinton won't actually be tested in the primaries, and she's polling behind potential Republican rivals in every match-up tested.

He also said that her email scandal won't sink her campaign in and of itself, but it did reinforce the idea that Clinton simply can't be trusted.
