From what I had been told, all these archaic rules were for the Royalty only.
POTUS is not royalty regardless of his wish to be.
All joking aside, the POTUS needs all the guidance, direction and help he can get. Lately he has been overheard repeatedly asking “Which way do I go?” when exiting the stage or trying to figure out how to get from point A to point B.
He was even photographed grasping the hand of Gretchen Whitmer, Governor of Michigan while walking into the event.
The Leftists have left us!
