The History of the Two-Party Vote

If you happen to enjoy demographic data being animated, like when Hans Rosling does it (here or here), or when a map shows you the march of democracy across human history, or even when a map shows you what Presidents were in office during different wars, then you are going to really enjoy this: an animation of the two-party vote system in the good ol' U.S of A. since 1920.

Now, I'm no serious student of American history, so I was really surprised to see when different areas of the country have professed their allegiance to blue or red ideals, and my guess is you'll be surprised too.

Now, did you know that Demography Today Magazine is now targeting demographer demographic? :)
