5:56 PM PT: John King asks Mitt Romney he's running an ad calling Newt Gingrich an "unreliable leader." Mitt Romney says he doesn't want to answer that question and at least so far, doesn't. Instead he mutters about not wanting politicians in DC.
6:00 PM PT: Romney did relatively well by not answering the question about his attack ad. But then a question comes about releasing tax returns. Ron Paul says he's worried that he'd be embarrassed about his tax return compared to the other guys on stage. Mitt Romney laughs lustily.
