At this very moment, an “unofficial” debate is taking place at the Denver convention. Every candidate — except Bob Barr — is participating. The venue is packed with the staffs and supporters of all the other candidates, but Barr and his staff are conspicuously absent. Sources tell me that Barr admitted to one of his well-known staffers that he chose to enter the race after the state conventions for the purpose of avoiding debates. Assuming he collects the requisite number of tokens, Barr will debate against libertarians — for the first time — tomorrow night.
