I think it would be worth looking up the definition of the word "objective," because it doesn't mean what you seem to think it means. Mikhail Gorbachev referred to himself in the third person, yet I think you'd be hard pressed to find many people who would consider him as narcissitic and self obsessed. I will agree with you that Trump is all three of the labels you've given him, but the mere act of referring to himself in the third person is not what qualifies him as such. Pretending to be reporters and hyping himself up would be more along those lines.

I'm also not sure where you got from my post that I don't think he's insane (assuming you don't mean insane literally). I think Trump, and Hillary, were both terrible choices for president. I simply disagree that thanking himself in the third person means anything significant, outside of the fact that he's more openly arrogant than his recent presidential predecessors.

Unless he talks about himself a lot in third person, I don't think it's really an indication of anything. If he does it only occassionally, it's probably just a rhetorical trick.

Neither

Look up the personality traits of a narcissist.

He's pretty much the text book narcissist. When a newspaper editor said he had small hands in the 80s, he made it a point to send the editor a letter with his hands drawn around them in gold ink explaining that he has perfectly good sized hands. He's been sending this letter every year since then apparently. 

All that needs to be said ... 

If Trump is a narcissist then all humans have that trait to a degree when it is in our psychological nature to be prideful ... (even those of a lower status must have some feeling of dignity left) 

Nope it's all him. I doubt he's paying someone to tweet for him at 3 AM. 

Both. I'm sure that he is up there. I think senility along with a raging ego is the final picture. But the real winner? Bannon. He has a mouthpiece to push his agenda with abandon.

 Actually narcissistic personality disorder is quite rare as far as diagnosis, but trump clearly suffers greatly from it. Atlantic magazine interviewed a bunch of psychologists, including some from Harvard. They said that almost all presidents have displayed an ego, but trump it's all the hallmarks of a textbook narcissist. They showed a breakdown of trump all the way to clinton and broke down how badly trump is polarizing in ego size. 

That's bullshit. I've never invented a fictional character nor masquerade as a fictional character to brag about myself.  Trump felt the need to concoct fictional spokesmen named John Miller and John Barron,  so that he could tell tall tales…so that he could brag about himself, his business and his conquest of women.  Such insecurity as Trump expresses, from the need to invent fictional characters, and masquerade as those fictional characters, to telling the world that he doesn’t have small private parts, is a sign that he has a mental problem that goes well beyond clinical narcissism.
