You probably caught The Daily Show last evening but if you didn't, I'd like to recommend Jon Stewart's interview with Stephen F. Hayes, author of a new book on Dick Cheney. There's something very refreshing about some of Stewart's conversations, especially with people he disagrees with. Obviously, he dominates. It's his show, his studio audience. He controls the editing. (It looks to me like they sometimes let an interview run a little long, or at least until it reaches a good end point, and then go back in and chop something out to get it down to time. There was at least one big jump cut in the Hayes interview.)
But what impresses me is that Stewart tries to engage people in a real discussion. I don't think anyone can come on his show and give stock, pre-scripted answers. He doesn't ask them the obvious questions…which means they have to listen, they have to answer and they probably have to think a little before they answer. A good coach could prep you for an appearance with Larry King or Tim Russert or even Bill O'Reilly but I don't think they could rehearse what you'd be saying opposite Stewart.
His discussion with Hayes was fascinating and I'd recommend it to anyone who still supports the war and doesn't "get" one of several big reasons why people are so mad about it. Basically, Stewart referred to the video clip making the rounds — this one, of Cheney in 1994 saying that the U.S. should not invade Iraq because it would be a quagmire — and asked Hayes why the later Cheney didn't acknowledge what the '94 Cheney knew. It's a good question and Hayes had no real answer.
I'll post a link to a video of the interview if and when one is available somewhere.
