Political Geography: Really wonderful analysis of the U.S.'s geographical breakdown in terms of politics and voting (these two terms don't exactly represent the same thing). Rather than just say "soda v. pop" or "red v. blue", this map breaks our country into ten divisions which do not always correspond to just one geographic region. It's based on the 2000 election results, but also by income, age and race. Really well done.

Props to Sullivan.
