So far, we don't know much about Romney's tastes in food, aside from the occasional ice cream scooped from Bailey's Bubble in Wolfeboro, N.H., and his affection for feeding Jimmy John's subs to the press on the bus. However, parsing the eating habits of presidential candidates (to say nothing of sitting presidents) is now firmly embedded in America's cultural milieu. Just think: Ronald Reagan and jelly beans. Bill Clinton and fast food. President Obama and, well, most things chili-related, plus a bit of home-brewed beer.
