The first presidential debate lasted 90 minutes, but President Joe Biden had lost it within 10 minutes. He stumbled immediately, lost his train of thought, and fell silent. It was painful to watch and obvious that no matter how much preparation he had done, he was utterly incapable of stringing sentences together and making a coherent argument.

It allowed former President Donald Trump to deliver a knockout punch within just 15 minutes of the debate beginning. After listening to Biden give a rambling answer on illegal immigration in which the president promised a “total ban” on something, Trump was given an opportunity to respond and simply said, “I really don’t know what he said at the end of that sentence. I don’t think he knows either.”
