This is one of the smaller of the numerous massive reasons why Trump would be a bad president:
He seems to believe that he can make something “true” just by repeating it. One frequent charge against Trump is that his temperament is not suited for the office. His response? “I…have a much better temperament than she has.”
I love that the audience laughed at him. He’s so used to syncophantic audiences, I think that took him by surprise. But he still probably believes that if he repeats it enough, it will become “true.”
