ELECTION 2006: America in Blue and Red

Hat tip to Pam at The Blend for posting this picture from the Facing South blog:

The image above shows the Congressional majority vote tallies by party registration (Blue for Democratic, Red for Republican) in every County in the United States. Pretty different from the 2004 Presidential results, eh?

Apparently, the 2004 Congressional county-by-county results are not available as a map. Interestingly, apparently there is a bias in the human eye which responds more to red than blue. The more unbiased way to present the information would be to use black and white and grayscale.
