Sorry, but this old populist chestnut strikes me as lame. I don't even buy Cunning Realist's defense. Knowing the price of a supermarket item is not and will never be an important issue for a man or woman seeking to be president. If you're going to give them pop-quizzes, at least ask them about the differences between Shiites and Sunnis, the presidential candidates in France, or how they define torture. We're not asking them to be CEO of Safeway.
