F1,
Trump is a polarizing figure, for many of the reasons you outlined. Hard to find many people who are neutral about Trump as a person.

Trump is a cash cow for the American media, left leaning and right leaning. He's been that for about 12-14 straight months.

Less of a witch hunt, than a cash grab. Anything related to Trump is going to be "breaking news" in electronic media or front page news in print.

I'm convinced that if any major news editor had the smoking gun that could implicate Trump in anything solid.....that they would NOT release it right away. They'd sit on it and slowly leak it in a way to maximize the amount of views/subscriptions/hits it would draw.
