For all political junkies this study of the 2004 presidential election by Michael Gastner, Cosma Shalizi, and Mark Newman is extremely interesting.
Update: It seems that the authors have gotten rid of the final histogram which claimed that 302 counties voted nearly fully for Kerry (IIRC >90% of the vote for Kerry.) This was the most interesting part of the article, unfortunately. Still an interesting article, but not nearly as shocking.
Shoot. I can’t see any of their images. And I really like cartograms!!!!
