Bush (both of them), Obama, Biden kept their pants up. But somehow Clinton and Trump got more widespread long-lasting supporters. (Also, neither Clinton nor Trump - and I’m guessing not Huang - waited until they were old to have affairs; it was a whole-adult-life problem, not an “old man” problem.) Seems to be a problem with the people choosing the men as leaders - there are moral men to choose from if the voters or board members or whatever humans are doing the selection wanted.
