10:37 PM: That was a really weird encounter between Perry and Romney on who's the biggest flip-flopper. I mean, this should be one you can just hit right out of the park for anyone running against Romney. And Perry was clearly prepped with a series of attack lines. But he stumbled over them like you'd woken him up in the middle of the night. Or maybe he was a punch drunk heavyweight at the end of the 14th round. Then Romney comes in -- an amazing flip-flopper if there ever was one -- and manages to just run circles around Perry. It was almost sad. Romney was on fire. And yet, Perry's clearly this audience's guy. He's got the positions they like. Romney basically doesn't. He says he does. But people don't really buy that. So how far does the complete debate mastery go?
