It's an impossible task, still try to put yourself in Trump's shoes knowing what you know about him, how he thinks, and what he faces when he leaves the presidency. He may see himself with a fight on his hands, but i can't see him being even close to being resigned to losing. We can't know what, but he would be setting some more dastardly deeds up as best that he is able to.
It was Plato who said, “He, O men, is the wisest, who like Socrates, knows that his wisdom is in truth worth nothing”
