Pretty keen blog devoted to the geography of elections, particularly this election. Some neat maps and links to other sites regarding maps and tools that others have done regarding the political and cultural landscape. Worth a look-see.
Also, if you’re inclined, check this one out too. Common Census is a site that invites citizens to enter information about themselves regarding their regional perspective and then maps the results. Some of the maps are just for fun, like the professional sporting team loyalty maps, but others show the extent of influence of major urban areas. Some neat stuff there.
