We have reached the final week of the presidential elections course. This week, Martin Lewis slices and dices the electoral results of the ’08 election and highlights the big and potentially far-reaching shifts in US voting patterns. No doubt, this is one of the more detailed analyses that you’ll find on the web. You can watch the last lecture in higher resolution on iTunesU here, or watch it below on YouTube. The complete course will be permanently housed in our collection of Free Online Courses under Geography and Political Science.
