If you look carefully at the videos of Joe Biden and Barack Obama when they are campaigning it is very clear that they can't function without a teleprompter and someone to tell them what to say. That was clearly evident during the first debate. President Obama was not able to function on his own without help and coaching. His dismal failure and that of Joe Biden makes it very clear that they cannot think for themselves. What is even more evident is that Joe Biden puts both of his feet in his mouth ins spite of having the teleprompter there to tell him what to say. I guess the coaches off camera can't think for themselves either.
The format of the first debate should be used for all candidate debates. Silence in the room, and no teleprompts
