The Geography of US Presidential Elections keeps rolling along. With his well-crafted lectures, Martin Lewis shows you this week how America's political map and its political parties changed dramatically following the Civil War. In the space of 90 minutes, he takes you through the Reconstruction period, The Gilded Age, the Depression, World War II and The Cold War, up through the Vietnam War.
You can download Lecture 3 via Tunes U in high resolution or watch the YouTube version below. And, as always, you can join the ongoing conversation with the professor and other students worldwide right here.
There are still two more lectures to come, including one that will offer a postmortem of next week's election.
