He claimed 3 million illegal votes during an election he won. 3 million... then what did he do once becoming president after an accusation of the largest voter fraud claim for a democracy in history? Nothing. Barely mentioned it. No enormous investigation to arrest the thousands of people that would have needed to be involved to coordinate 3 million illegal votes. Nothing. Why? Because it was just something for him to say off the cuff. He took a page from his hero Roy Cohn to just declare victory even when defeated. Lose a case? Just claim victory. Lose a popular vote count? Just claim victory. He has done it all his life and doesn't care how easily it is for some people to believe his off-the-cuff lies even when they can threaten democracy itself. He will never concede a loss and doesn't care who it hurts. He will also never have the evidence for his claims because he doesn't need any.
