The issue of whether Donald Trump is mentally unfit to be president — or, put more bluntly, whether he suffers from a serious mental disorder — isn’t one to be taken lightly, yet it sometimes seems destined to be tinged with comedy. In 2017, when speculation about Trump’s mental state was first reaching full boil, Allen Frances, the psychiatrist who wrote the criteria that defines narcissistic personality disorder, published a righteous letter in The New York Times insisting that Trump was not an example of that syndrome. I looked up the criteria on several prominent medical websites, and guess what? Trump meets every one of the criteria. (Don’t take my word for it; look it up yourself. That letter to the editor read like Freud coming back from the dead to claim that the Woody Allen character from the ’70s was not, in fact, neurotic.)
