Here is a story that has bothered me for some reason, but seems to have been taken by the mainstream press as just a minor aberration in Donald Trump's behavior. Trump has a visit to England planned in the fall. As part of his trip, he has demanded that he be allowed to ride along with the Queen in the royal coach.
I commented a little while ago about Trump's replacing his top advisers one by one with members of his own family. My thought was that, as he has taken power, his megalomania has grown, and merely being President is not enough for him. He is coming to think of himself as the founder of a dynasty, or to be blunt, a King rather than a President. Seen in this light it is hardly surprising that he is now insisting that he be treated exactly like real royalty. Expect to see more of this sort of thing, as his frustration with the limitations of his position grow, and he attempts to assert his right to do whatever he damned pleases, even to the point of handing the country to his family in perpetuity.
