I have to admit that I found the British moderator no better than the panel members

I agree that Dimbleby (the moderator) was very weak at keeping people to the question. He did attempt to insist the panel answer the question a couple of times and then appeared to give up all hope of doing so, being content just to get to the end of the programme. This had the possibility of being an insightful programme and ended up as perhaps the poorest edition of Question Time I've seen.

I think it was unwise of Michael Moore to do the show at all, though. He hardly needs either the money or the publicity and the risks of saying or doing something that could be exploited against the Democrats were very high. The only way of avoiding that was to do and say as near nothing as he could manage, which seems to be what he tried.
