To some, Bill Clinton was the "smartest president ever". Well, it was apparent a decade ago that Big-Mac-eating Clinton wasn't too concerned about his diet then.
I would imagine that Hillary is responsible for Bill's dietary problems. I can never imagine her cooking him anything to eat, and he probably waited until the last minute to eat, which meant "fast foods." Remember, he is notorious for his procrastination and tardiness, in contrast to the now rebounding GWB. Besides, Clinton knows that God watches over him through all things and is always forgiving.
