so far tonight

I like how Obama made sure to get the first response in before Leher would finish asking the question by repeating the first syllable of his response - it really put McCain on the defensive and shortened his speaking time. The first speaker has the freedom to frame the answer, while his opponent has to counterpoint before offering his opinion. It's much harder to get your message across when you have to first address someone else's, then cycle back to your message.
