Here is a short definition of “narcissistic personality disorder” based on the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5), the official psychological diagnosis manual:
Has a pervasive pattern of grandiosity. Needs and requires excessive admiration. Has a grandiose sense of self-importance. Exaggerates achievement and talents. Expects to be recognized as superior without commensurate achievements. Is preoccupied with fantasies of unlimited success. Has a sense of entitlement. Lacks empathy. Takes advantage of others to achieve his or her ends.
Does this not describe Donald Trump perfectly? What does it say about America that millions and millions of people think he should be the president of their country?
