• There is no data for 181 out of the more than 3000 counties in the US. I think these counties are mostly contained in districts in which the race was uncontested. These counties are colored according to state-wide data rather than county-wide data.

District-by-district election results for the 2006 Congressional races.

Notes:

• There were 34 uncontested races. Those districts are painted pure red or pure blue depending on the party of the incumbent.

Same district-by-district map recolored to show margin of victory.

Notes:
