At first I thought that the term, "madman" was extreme and inaccurate. But the more I think about it, the more inclined I am to agree, though not for the reasons given by the shrinks.

What's 'mad' is that Trump has viewed himself as presidential material. At our age (I'm only a few years behind him) most of us know our weaknesses. In his case, he is prone to exaggerations and outright lying, he is impulsive and exceptionally self-centered & narcissistic, he has a checkered past that he knows will be scrutinized and he proudly presents as a bully & a self-promoting braggart. 

None of this is compatible with the office of any national leader, yet Trump had the gall to seek it. Either he is unaware of his own deficiencies or he has misunderstood the awesome responsibilities that he has assumed. More likely, he has grossly miscalculated on both counts.

He will almost certainly be seen as the least fit of all presidents for decades to come. Inviting such a legacy is a crazy thing to do.
