You can have issues with Trump, but if your issues with him are "he's a sexist pig, and he insults members of the press" and then you go on to act the same way while never addressing why you now consider this acceptable behavior, then I'm going to question your motivations. Especially if you're a professional pundit.

All it would take is an article: "Why I was wrong in this article I wrote in 2016". Maybe he's already written this; if he has then I take back what I said.
