Needless to say, I highly recommend the article. Conway lays out a careful and detailed picture of how Trump is seriously impaired by several psychological deficiencies, including a narcissistic personality disorder, antisocial personality disorder, and sociopathy.
It's not a short piece but it's one of the best articles on Trump I've read. If you don't have time to read it, I recommend downloading the audio version of the article for your personal media device — that link can be found on the article link above. The article in its entirety is read by a professional voice actor who really brings the piece to life.
If you have the time, I also recommend downloading and listening to former federal prosecutor Preet Bharara's excellent program (link here) where he interviews Conway specifically about his article. Conway rarely sits for interviews so it's a really fascinating program.
