Somehow we’ve fallen into the habit of talking about “red states” and “blue states.” Actually, the original map of the reds and the blues was a map of counties. It was the power of a map with vast stretches of red and only tiny patches of blue that brought home the idea of a cultural divide. The real gap was between a few urban areas and most of the rest of the country. Even in many “blue states,” its only a few densely populated counties that are truly blue. So here’s a job for someone. Do a red and blue map of Bush and Kerry counties, then compare that map to the original from 2000.
