As I was watching the debate, I thought it was a terrible question and I thought that Ron wasted a good opportunity. However, after further review, I think it was great! McCain clearly had no idea what he was talking about and he looked like fool trying to bumble his way through the answer.
There is a chance, albeit a small one, that the media will pick up on this since they were hitting him last night regarding his denial of the "I'm not good with economics" quote. I think that's what Ron was looking for. He wasn't trying to look great with the question, but rather, was trying to put a question out there that would make McCain look foolish and let the media talk about it for a few days.
