Former Massachusetts Governor Mitt Romney
His hair was messed up at the debate's start (very humanizing, very un-Mitt), but it seemed to be quickly smoothed off-camera. Got to talk about his opposition to gay marriage, a subject on which he consistently shows passion. Tried to clean up his horrid "first thing we do, let's consult the lawyers" answer from the last debate and embraced his Massachusetts health care plan with a little more brio than usual. Still, seemed vaguely rattled at times and a bit lost.
