It is a serious post, and I've never watched/listened to Hannity for one minute of my life. Obama with a teleprompter is one of the best public speakers in history - which is definitely a tough skill and in no way a knock on him. Many people, including a lot of politicians, cannot do it well, and I don't think I have ever seen anyone do it as well as Obama. But, it is a completely different skill than functioning in a debate setting. The teleprompeter gets rid of most of the "uuhhhh"s that he was stumbling over last night as he was trying to formulate his responses. The few times that he completely ignored the question and launched into an unrelated scripted diatribe, were the few times that he was okay.
Clinton was probably the best I've ever seen away from the teleprompter. When he was asked a question, he would remain silent for about 4 seconds and you could see the wheels turning as he outlined the next 2 minutes in his head before he said a word. Then he would lanuch into it and flow through it eithout hesitation like natural speech.
