text:  There's a man I've seen at just about every debate I've covered over the years. That is Aaron Call. He is a head of debate at the University of Michigan. He's an expert on debate. He's in Atlanta tonight to watch this unfold. And Aaron, always good to talk to you, my friend. You're an expert on the finer points of debate. Can tonight be a real debate? Or if you were coaching the candidates, would you tell them this is about their performance?
