They may be referring to this picture.
Picture tells a thousands words. Cheating Bill left out in the rain. Even his daughter would rather share her umbrella with another man. A real man, at that. One who doesn't cheat on his wife and one who does not engage in sexual activity in the White House with young tarts.
Whenever I think of Bill Clinton in the White House, I picture empty pizza boxes scattered around with Monica under Bill's desk pulling his pants down while cruise missiles sail into empty tents in Afghanistan and Sudan. Then I think about the Twin Towers falling down in New York City a few years later on account of Bill's incompetence and dereliction of duty and I get angry.
BTW, Where was Al Gore with his two umbrellas?
