We all know that Trump uses his powers of outrage to make his orthodox, plutocrat-friendly positions on taxes and regulation palatable to the Reactionary wing of the GOP. The irony here is that Biden, if elected, is likely to do precisely the opposite. He will use his reputation for good sense and moderation to help sell very progressive positions on taxes, child care, health care, and climate change to the general public.
Sometimes it’s the salesman, not the product. Trump would be happy to tell you that; it has worked for him all of his life.
