Mitt Romney actually said...

"He's always self-editing in an odd way."

"Governor Romney told CBS News tonight that it was not meant as a swipe at the president; it was just a joke, he said, because he was back home in his birth state of Michigan."

"If you come up here and look, the moment, a statistical dead heat among independents, Governor Romney with a slight edge."

"Ann and I were both born in Detroit. A little humor always goes a long way. It was great to be home, to be in a place where Ann and I have grown up. And the crowd loved it and got a good laugh."
