Like it or not Trumps public approach and style offended many even though they voted for him. Even his family understands this hurt Trump. They wanted him to be more “Presidential” and did not understand the nation needed a fighter.....a tough one.....and those people still would want him to tone things down a few notches. He would have to show his ‘leadership’ qualities in public as he did in meetings and with International leaders....up front.
I agree with your assessment. I voted for Trump and donated generously to him but at times wished he would have toned down the self-centered antics and struck a more presidential tone. Such mannerisms tended to turn people off, even those who supported his agenda and sympathized with with him in his battle against the entire DC Swamp.
He was entertaining and fun to watch but he also generated lots of resentment from people who didn’t like his combative style. I know a few of those people. There is no question in my mind that his outsized personality hurt him during the election. You simply can’t afford to alienate anyone when you’re in a tight race.
