Mmmmmm ... graphical representation of data.

If you're at all interested in U.S. politics and/or the graphical representation of data, you'll want to check out the interesting work of some physicists at the University of Michigan.

They basically play around with the standard red vs. blue state/county maps that are used to display election results at-a-glance. They make adjustments for population (e.g. see below) and electoral college votes, and they take a crack at compensating for the fact that these maps typically take a winner-takes-all approach to colouring a particular state or county, regardless of the actual vote split.

There's another fascinating series of cartograms explored in this blog post: "purple" maps, maps that use white as the centrum and shift to blue/red, various map weightings by population ... fascinating.
