For example, which of these maps more accurately represents electoral America in 2004?
The first is a familiar red/blue (GOP/Dem) map by electoral winner where each state is represented by its geography.
But elections aren't about geography; they're about voters. And the second map, where states take shape based on population, is a far more accurate representation of the 2004 results.

Thanks to Matt at Snarkmarket for the pointer.
