That's one thing the presidency is about -- Michelle Obama says:
According to that standard, who are the 5 greatest Presidents and who are the 5 worst Presidents? This will take deeper knowledge of history than I can summon up right now, so help me out. I'm just going to guess that these lists have little relationship to the achievements of the various Presidents. But it is warm and pleasant to have a charming, conventional, devoted family snuggled up in the White House, and we don't like to picture any semen splattered about. That upsets us.
