Mitt Romney has made a point to emphasize his support of George W. Bush and the Bush administration in most matters. But today, at an appearance at a corporate office building in West Des Moines, he criticized Democratic proposals for government-run health care by saying, “I don’t want the guys who ran the Katrina cleanup welcoming me into the emergency room.”

Romney also tried out a new joke, aimed at Huckabee campaign chairman Ed Rollins, who famously said he wanted to knock out Romney’s teeth. “I have just one thing to say to him,” Romney said of Rollins. “Don’t touch the hair.”
