Politics aside, he just needs to retire at his age. (As do all people in positions of influence at that age.)

Getting old is a thing, unfortunately. Various privileges should be limited as cognitive decline increases. Driving, politics and even restrictions on physically demanding jobs are the first things I can think of that need to be pulled back from people. (Comprehensive and standardized cognitive testing may be an option? Not all people age the same way, obviously.)

Yeah, I’ll be old soon enough and will probably be kicking myself for saying the above in due time.
