Back when Reagan was president members of the press knew that the man had some form of dementia, that he was not actually fit to run the country, and they covered it up because the feefees of America would be hurt because Reagan was the most popular president in the history of the universe. Of course he wasn't the most popular president by any reasonable measure, but the press loved him so America loved him and they added 10 extra points to his popularity rating in their minds. They did that for Bush II, also, too.
I don't expect Trump will ever be an especially popular president for a variety of reasons, but with the 10 bonus points traditionally granted to Republican presidents, who knows what must be kept from America. Because of our feefees.
