I think Trump cares about getting elected a whole lot more than winning in court. People who support him often do so because they identify with his victim role.
I am not sure how to respond to your statement for a couple of reasons. The attempt, without evidence, to impugn Willis in some sort of job related corruption was not done by Trump, but by a fellow alleged conspirator, Mike Roman. The opinion I expressed was directed at him.
But, leaving that aside, I am not sure how to evaluate your statement. I see Trump as a person whose fear of failure is so great that he lives in a completely delusional state, one in which he is actively playing the role of a prosecutor in a perpetual role of the hero who dolls out retribution for all the wrongs done to him.
I see his appeal as one that resonates with the feeling of victimization we all feel for having been made into victims ourselves by being put down as children as worthless. What I see as his attraction to people is their own lust to get even they are too emotionally unable to express. He is a representative of the disease they long to be, the very thing they came to fear and now calls to them to join in getting even.
So, in my opinion Trumps mental illness is so profound and complete any and all slights to his ego, losing in court, losing an election, losing a golf match are all the same, they will be met with maximum resistance, maximum retribution and absolute denial. He is a victim that has mastered the art of getting even. Trump is a role, a gold toilet, a front, a pretense of greatness born from utter self contempt.
I guess it would be fair to say hey caring more or less about different issues that he has priorities. But I bet he sees a criminal conviction as a potential threat to getting re-elected.
