Herman Cain and Ron Paul Clash Over Favorite Fed Chairmen

Herman Cain on Tuesday night called Alan Greenspan the best Federal Reserve chairman and said he had "two candidates waiting in the wings" to replace current Fed chairman Ben Bernanke.

But Ron Paul called Greenspan "a disaster."

"We shouldn't have someone deciding how much money we should have. Greenspan created the biggest bubble, and Bernanke has only compounded the problem," Paul said. "Paul Volcker at least knew how to end inflation."
