Visual Presidential votes for the last 88 years

This is a visual representation of the red/blue map of America for the last 88 years by David Sparks. David Sparks is a PhD. candidate in political science at Duke University.

From David Sparks' blog:

"This animated interpretation accentuates certain phenomena: the breadth and duration of support for Roosevelt, the shift from a Democratic to a Republican South, the move from an ostensibly east-west division to the contemporary coasts-versus-heartland division, and the stability of the latter."
