Narcissist

HuffPo: Too Sick To Lead: The Lethal Personality Disorder Of Donald Trump

With Trump ever in mind, try these. An exaggerated sense of self-importance. An unwarranted belief in your own superiority. A preoccupation with fantasies of your own success, power and brilliance. A craving for constant admiration. A consuming sense of entitlement. An expectation of special favors and unquestioning compliance.

A penchant for exploiting or disparaging others. A total inability to recognize the needs of anyone else. An incapacity to see those you meet as separate human beings. An unreasoning fury at people you perceive as thwarting your wishes or desires. A tendency to act on impulse. A superficial charm deployed to disguise a gift for manipulation.

(Note - this is just part of it.)
