On "Special Report" tonight, Charles Krauthammer reacted to Bernie Sanders' surge in the polls and the Vermont senator's effort to reach out to African Americans.

"I think the reason that he's been rising is because he isn't an outsider in the sense that he's a non-politician, but he's been completely insignificant," Krauthammer said. "He's been in the Senate. Has anybody even mentioned him until now? Has he achieved anything? Has he passed a bill? Has he made a speech in a quarter century?"

Krauthammer noted that Sanders is now courting African Americans and other minorities by talking about income and social inequality. Krauthammer said that would work, except Sanders' party has had a president in office for seven years and done nothing.

"So, only a man who's been inconsequential out there, hiding in the back of the benches, is a man who could make that case."
