As mentioned last week, Stanford is hosting a five week course, The Geography of US Presidential Elections, that you can follow (for free) in real time. The first video lecture is now available on iTunes (download here), and you can find it embedded below.
The first lecture is fast paced, and features intriguing graphics that start to dismantle the widely held belief that the US can be neatly divided into red and blue states. I will keep posting the lectures as the course unfolds. In the meantime, I'd recommend visiting the course web site, and asking the professor, Martin Lewis, any questions you might have.
