"There’s a hidden danger to authoritarian leaders in all this. When they discover their followers will believe anything they say, even things that contradict something they said earlier, they get sloppy with their lies. Maybe Donald Trump always was careless with the truth. But it seems that over the past two years he has become downright reckless. His base will swallow anything, he has learned, so he just says the first thing that comes to mind. The trouble is, for him and the future of his presidency, Truth happens. Constantly. It may be seen differently by various folks, but things did happen as they happened, not something else. You can only ignore the truth so long, and then reality will inevitably catch up with you. It will destroy you if you have been massively denying it."
