THIS is what we mean by "normalizing the lying". Yes, all politicians will lie...but they tend to lie about things that benefit them. Trump, on the other hand, lies about everything whether it be large, small, relevant, or irrelevant. And it's the horrendously huge amount of lies he tells that is so revealing. He lies just o lie. He really can't help himself. It's just part of who he is.
In a scene from Murphy Brown, she ask her version of Alexa/Echo how many times has Trump lied. Alexa gives her an answer then immediately has to keep updating the number. The amount of lying Trump does is WAY past the number we expect from politicians and into the realm of absurdity.
