The ultimate debate, when it comes to wit, humor, and intelligence was between Gore Vidal and Bill Buckley. You don’t need a moderator in a debate like this and there really wasn’t one, with Howard Smith letting Vidal and Buckley basically just go at it because the two men could carry the conversation by themselves and knew where to go and what they wanted to say. They also both listened to each other and knew how to respond to their opponent’s legitimate points in an intelligent way.
It would be nice to see more debates like this, with two people literally just going at it and no one asking questions but just giving them topics to talk about. They already knew what to say because they knew what they thought. That should go without saying, but a lot of politicians and candidates either don’t know what they think or do not know how to express it in a way that doesn’t hurt them politically, so they are afraid to say what they think.
