In any nation but the USA, it is taken for granted that a man of distinction, ability, wealth or power will keep a mistress and a few girlfriends on the side. Only in America, still suffering from its grotesque, hypocritical Puritan heritage, do we persist in attempting to deny and repeal a million years of basic primate biology.
Washingtonians love the "So-and-so is spinning in his grave" cliché. Someone is always speculating about how some great dead American would be scandalized over some crime against How It Used to Be. The Founding Fathers are always spinning in their graves over something, as is Ronald Reagan, or FDR. Edward R. Murrow is a perennial grave spinner in the news business (though in fact, Murrow was cremated).
