The 2010 Results Swingometer shows the swing in the two-party vote from the 2008 House elections to the 2010 House elections.
The Swingometers use Javascript and SVG, and are only tested so far in Firefox, Safari, Safari Mobile, and Google Chrome. Android 2.x and earlier users may need Firefox. Older versions of MS Internet Explorer probably can't handle them. Opera might. Blackberry users are sent my condolences. Please feel free to hit the Contact form with bug or success reports.
How to read the chart: Red districts went more Republican in 2010 than in 2008, while blue districts went more for the Democrats. Bright blue and bright red districts saw large shifts, while darker, more purplish seats had smaller shifts.
