 Look at what happened in my home state of Pennsylvania in the U.S. Senate debate between John Fetterman and Mahmoud Oz. Fetterman couldn't even read from the teleprompter, even when given a teleprompter. Did it matter to his voters? Not at all. The same would be true of Joe Biden's self-destructed on national television. In other words, Donald Trump has nothing to gain but much to lose from the debate. He has been ahead of Biden in the polls since October.
