I'd agree that her appearance is amazing to watch, but only as it illustrates how her adherance to conventional media tactics ensured her failure as a messenger. Stewart is (unconventionally) asking questions and pressing for answers. McCaughey tries to answer questions that weren't asked so she can get her talking points in. Despite the fact that both were heavily prepared for the interview, Stewart appears earnest and McCaughey looks like a fraud. To be fair, Stewart benefits from being the person asking the questions (as well as being a satirist) - but McCaughey's inability (or outright refusal) to engage in clear discussion discredits her and her viewpoint.
