They all pay a price in political capital and legacy. Why shouldn't trump? His insistence that he be treated differently or special is delusional, one of his several mental illness issues.
So then, you must believe Obama mentally ill too. Right?
No, Trump is pathological and delusional. He tells "beneficial lies", that is, lies made and designed to benefit an individual's narrative, which is relatively common, but he also tells "impulse lies", lies made from simple insecurity and basically trivial reasons of generally unimportant matters.
