Andrew Sullivan says Kerry seemed "bigger"--a Presidential Height Index effect? The quote:
"KERRY'S MANNER: It was, as I hoped, an enlightening debate. No, it didn't include any real logical breakthrough and on the issues, I found myself agreeing more with Bush than Kerry. But from the very beginning, Kerry achieved something important. In tone and bearing, he seemed calm, authoritative, and, yes, presidential. I watched the C-SPAN version on a split screen, and in that context, it was particularly striking. In stark contrast to the Bush-Gore debates, it was Bush who was grimacing, furrowing his brow, almost rolling his eyes and at the very beginning, looking snippy and peevish. He seemed defensive throughout and because his record was front and center - and Kerry's long record in the Senate almost unmentioned - he was actually on the defense. He seemed physically smaller and more mobile than Kerry - and more emotionally alive. Their voices were contrasts too. I can see now for the first time why Kerry has a good reputation as a debater. It wasn't, I think, because he debated well. In fact, he debated poorly. He failed time and again to go in for obvious kills, failed to do what he really should have done, which is skewer Bush's conduct of the war, not his decision to launch it in the first place. But his tone was strong, clear, unwavering. And in some ways, this was critical to undermining Bush's constant assertion that Kerry is weak, vague and inconstant. In fact, Kerry didn't have to prove logically that this was the case (which would be hard to do); he undermined it merely by his tone and manner. For many people, who have only heard of Kerry from Bush ads or sound-bites or from droning campaign speeches, it will be the first time that Kerry seems strong. In the simple, symbolic man-versus-man contrast, Kerry often seemed bigger. That strikes me as a big deal. "
