[edit] Summary

The congressional district boundaries for Georgia and Texas are incorrect in this map. Boundaries for these states were redrawn between November, 2004 and November, 2006. These new boundaries were in effect for the 2006 general election for the 110th US Congress. See: [1] and [2]

This map indicates the margins of victory (1st place candidate over 2nd) in each of the 435 districts of the United States which elected a Representative in the 2006 elections.

In 34 districts, the incumbent ran unopposed. These districts, along with Michigan-15 (the largest margin in a contested race), are at uniform intensity of color. Three districts in Alabama match this, in case you want to use a color picker.

There are no districts which are white in this image, but some are near white. The lightest are Florida-13 (R by 373 votes) and North Carolina-8 (R by 449 votes) which are #fffefe, and Connecticut-2 (D by 167 votes) which is #fefeff.

The closer to white the district is painted, the smaller the difference in vote totals between the winner and second place candidates.

These are the results as of early Saturday, November 11th. It will be at least a month before all official results are in, longer for some districts.

In cases where the race hasn't been called, I used the vote totals just as if they had been called. Chances are they are very close to white, and will remain so.

The runoff election in Louisiana-2 will probably cause that district to turn much bluer. Democratic candidates received over 80% of the votes in the first round.

I wrote the software that generated this file. The software takes election results, calculates appropriate shades of colors for each region (in this case, US House districts), and then paints the image. I also did tons of data entry and image manipulation to get this "base map" of the United States to paint. The maps, before I altered them (extensively at the pixel level) are from the US Census Bureau.
