It is interesting to read the bullet-point definitions for the "disorder". Mr. Trump seems to be hit by every bullet.
Wow, you are right. From the article:
* Feels grandiose and self-important (e.g., exaggerates accomplishments, talents, skills, contacts, and personality traits to the point of lying, demands to be recognised as superior without commensurate achievements);
* Is obsessed with fantasies of unlimited success, fame, fearsome power or omnipotence, unequalled brilliance (the cerebral narcissist), bodily beauty or sexual performance (the somatic narcissist), or ideal, everlasting, all-conquering love or passion;
* Firmly convinced that he or she is unique and, being special, can only be understood by, should only be treated by, or associate with, other special or unique, or high-status people (or institutions);
* Requires excessive admiration, adulation, attention and affirmation – or, failing that, wishes to be feared and to be notorious (Narcissistic Supply);
* Feels entitled. Demands automatic and full compliance with his or her unreasonable expectations for special and favourable priority treatment;
* Is "interpersonally exploitative", i.e., uses others to achieve his or her own ends;
* Devoid of empathy. Is unable or unwilling to identify with, acknowledge, or accept the feelings, needs, preferences, priorities, and choices of others;
* Constantly envious of others and seeks to hurt or destroy the objects of his or her frustration. Suffers from persecutory (paranoid) delusions as he or she believes that they feel the same about him or her and are likely to act similarly;
* Behaves arrogantly and haughtily. Feels superior, omnipotent, omniscient, invincible, immune, "above the law", and omnipresent (magical thinking). Rages when frustrated, contradicted, or confronted by people he or she considers inferior to him or her and unworthy.
