Take on the thin skinned pres.

Imagine having the most criticized job and pairing it with the thinnest skin. Trump has proven over and over again that the only joke he won't laugh at is one about himself which tells you all you want to know about him. Self deprecation is probably the best characteristic to carry in public life and he has absolutely none of it
He can't possibly be as dumb as he sounds but if he could at least own up to it, he's at least come across as half way human
