Election By Numbers

A statistical narrative of the 2010 midterms.

The election is over, which means it’s time for pundits to cram the outcomes into a narrative. But why let the talking heads have all the fun? Below are some of the highlights from the election—told by the numbers. Did the Blue Dogs lose big? Did Sarah Palin’s chosen candidates sweep their races? And how did incumbents fare in the most anti-incumbent election … possibly ever?

Election results are as reported by The New York Times on Wednesday afternoon. Palin endorsement data comes from The Washington Post’s Palin Tracker. Historical re-election rates come from the Center for Responsive Politics. Win rates were calculated by dividing the number of wins reported by the number of elections with a consensus winner announced. (Of course, some races are still up in the air, so those were left out for now. That’s why the math might not always add up perfectly.)
