IMHO, Senator John McCain came across as presidential, tough, and no nonsense. His basic overall message was, "I have the experience, I know the issues, I fought for reform, I understand the problems in Iraq, Iran, Russia, et cetera, and you don't."
McCain called Obama naive and inexperienced. Yet even as he did so, he always remained pleasant and seemed to be energetic and focused. Interestingly, he would not look at Obama, and he referred to him as "Senator Obama," while Obama called him "John."
Senator Obama appeared to be irritated, and he rambled (has he been spending too much time with Biden?). He also repeatedly said that McCain was right - nine times! A couple of times Senator Obama seemed to be looking beseechingly at Jim Lehrer as if to say, "Help me!" There were also a few times that Obama looked downright furious. It was kind of scary. (I thought McCain was supposed to be the angry one?)
Senator Obama was not happy when the debate was finished; you could tell he thought he'd lost. On that point, at least, he's right.
Favorite McCain quotes from Friday's debate:
"It's hard to reach across the aisle from that far to the left."
"So let me get this right. We sit down with Ahmadinejad, and he says, “We’re going to wipe Israel off the face of the Earth,” and we say, “No, you’re not”? Oh, please."
