Mark Newman is once again getting an awful lot of online attention for his maps and cartograms of the 2008 U.S. presidential election results; he did the same thing for the 2004 presidential and 2006 congressional results (see previous entry). The maps come in many flavours: ordinary maps showing blue and red states; maps showing blue and red counties; “purple” maps that show the degree to which a county is blue or red; cartograms for all of the above. Newman is all about the cartograms; he’s one of the authors of the cartogram collection, The Atlas of the Real World. Via many, many sources.

Other cartograms: Peters’s publisher ODT Maps has a grid-style election cartogram based on population rather than Electoral College votes (via AnyGeo); from the comments, this one weighed by electoral votes.
