Reagan perhaps. George Washington certainly.
The author makes an interesting distinction between a puffed up ego and narcissism, that challenges the idea of even blow hards of necessarily being a narcissist.
Every president is subject to them and found mentally ill by certain segments of the opposition. It gets old.
An even older and ubiquitous trend is for some to conclude the president is doing well, yet some conclude they are not, and yet others conclude its a mixed bag. However, old and common these patterns are, one of these groups is more correct than the others.
If you read the article, it says having narcissitic traits doesn’t make you a pathological narcissist.
Narcissim is a continuum as are all psychological traits.
Ding! We have a winner! Washington was offered the Crown and turned it down. Anyone with even the slightest narcissism wouldn’t have been able to do that. Reagan, too, was driven by his faith in God and America, both of which are literally incomprehensible to a narcisist (although they mimic the forms of faith VERY well if it suits their purposes).
