Via Sunlight Foundation Blog comes news of an interesting new project called RaceTracker.  It looks like Politics1 on steroids.  (But Politics1 has other offices listed.)

The RaceTracker project on the OpenCongress wiki tracks every election for the U.S. Senate, U.S. House of Representatives and state governor. RaceTracker is a free, open-source, fully-referenced, and non-partisan public resource.
