Apropos an earlier post, here’s Elizabeth Drew writing in the New York Review of Books:

Trump’s possible mental deficiencies are also a troubling question: serious medical professionals suspect he has narcissistic personality disorder, and also oncoming dementia, judging from his limited vocabulary. (If one compares his earlier appearances on YouTube, for example a 1988 interview with Larry King, it appears that Trump used to speak more fluently and coherently than he does now, especially in some of his recent rambling presentations.) His perseverating about such matters as the size of his inauguration crowd, or the fantasy that three to five million illegal voters denied him a popular vote victory (he got these estimates from a dodgy source who has yet to offer documentation), or, as he told CIA employees, the number of times he’s been on the cover of Time (sometimes inflating the actual number) has become a joke, but it also suggests that there may be something troubling about his mental state. Numerous eminent psychologists and psychiatrists have written about or expressed their concerns about Trump’s mental stability.

Another puzzling thing: many of Trump’s tweets have a slightly pathetic tone — things are “so sad”, “so so unfair”, etc. It’d be interesting to do a sentiment analysis of his Twitterstream. Hmmm…
