On Monday, David Cameron did something very brave. The British prime minister, facing what is likely to be an extremely close race for reelection May 7, went to a voter's garden and had a meal. Braver still, he allowed the British press to take photographs of him eating the meal. It sounds strange, but in Britain's election season, food-eating has become political. And it didn't take long for Brits to notice that Cameron was eating wrong: He was using a knife and a fork to eat a hot dog.
