Chris Matthews Endorses John McCain, Takes It Back (VIDEO)

Chris Matthews semi-endorsed John McCain Wednesday on "Hardball" and then immediately rescinded his endorsement.

"He's a great guy from Arizona," Matthews said of McCain. "He's in the tradition of Barry Goldwater. He's a maverick like Barry Goldwater was a maverick....Look, if my endorsement helps you, John McCain, you've got it. If it doesn't, throw me under the bus."

Moments later, Matthews took it back.

"I don't endorse, by the way," he said.
