The Sunlight Foundation blog, SunSpots, reports that the MAPLight MAPLight.org (creator of the great Presidential Money Race Widget) and and Congresspedia, a project of the Center for Media and Democracy and Sunlight, have joined forces to bring their data together so you can learn more about members of Congress all in one place. The partnership allows you to access background and source information as well as money in politics information on a legislator. For example, here's PA Sen. Robert Casey on Maplight, showing where he gets his money. If you click on the Congresspedia tab you can get complete background information on the Senator: biography, voting record, etc.
