Several things I noticed from the debate...agree or disagree with me and draw your own conclusions...
Cooper tended to hand questions off to the 4 "major" candidates: Romney, Guliani (sp?), McCain and Thompson. Huckabee got OK air time as well. On questions asked off all the candidates, each should have had an opportunity to answer. Instead very little was heard from the "minor" candidates. Take the question on their gun collection. The responsible, ethical and fair way to field that as a moderator would be to start at either end of the stage and work to the other. It didn't happen.
The questions picked by CNN, especially for Paul, were ridiculous. 2 of his completely belittled him, IMHO. In the interest of fair disclosure, I am a supporter of Dr. Paul's. He has a reputation amongst many as a tin foil hat kind of guy. One of his 4 questions from the you tube submission was on the North American Union and so called conspiracy theories. Another said he wouldn't get the nomination, so would he run as an independent. The other "minor" candidates seemed to get the questions that were of little importance to the major issues in this country. This complete degraded the concept of a debate for the people, by the people, which seemed to be be CNN's premise.
