Weekly blog map #9: Election Map

Less than a week till the big 2012 presidential election. Every news organization and loads and loads of other sites have their own versions of how the polls map. Although Presidential election data is most popular, any upcoming election info is fine. For this posting, an interactive map is okay. Find a map you particularly like and explain what sets it apart. 

Since this is *color* week...how does the map you selected use color? If it is qualitative data, do the colors really appear even visually? Does a particular color have a slight bias?
