Susan's right. It's amazing that McCain wanted 10 town hall meetings with Obama when, in fact, the format last night only highlighted his age. He moved with stiffness around the stage, I guess in large part because of his war injuries.
But viewers could not have missed the stark comparison between the two candidates in physical vitality. The 72-year-old looked it. Personally, I think McCain held his own in answering the questions, particularly if you read the text of the debate. But video images are hard to shake when you think about choosing the person to fill the world's toughest job. CNN has a handy replay feature that gives you both text and video.
