Barack Obama, Hillary Clinton, Ronald Reagan, Dwight Eisenhower and probably every politician ever has used spin or told some whoppers to achieve a specific goal. But the benefit from the stories Trump has spun recently was not only zero, it harmed him. No rational person could possibly have cared how many people attended Trump’s inauguration; anyone could see the same photographs and read the same data about television viewership and Washington’s mass transit usage as everyone else. None could have reasonably believed that the most incredible voter fraud campaign in American history had just taken place, with millions of illegal votes cast for Democrats, particularly when Republicans won most of the key Senate races in that election and maintained control of the House. He could have said nothing about those two topics and no one would have thought the worse of him. But if he knows he is lying, he not only accomplishes nothing, he harms himself by showing he will lie over irrelevant trivialities. And that raises the question of whether he knows when he is lying.
