Last week Ruy Teixeira and William Frey presented data from their project on the political geography of the 2008 presidential election. Unfortunately, it was on the other coast, and I was not able to attend. But Ruy sent around the url to the presentation that he and Frey gave, “The Political Geography of America’s Purple States: Five Trends That Will Decide the 2008 Election.” It’s an interesting report, worth downloading and reading.
There are also a series of detailed reports that they have done on the battleground states; you can obtain the detailed reports at the Battleground Dynamics Series page.
