Watchdog API

From their site: watchdog.net lets you find out what's going on in politics and make your voice heard about it. We're trying to build a hub for politics on the Internet. Data: there's a lot of great information out there about politics – district demographics, votes, lobbying records, campaign finance reports – but unfortunately it's split across a dozen different web sites and often hidden behind confusing interfaces. We're pulling all of that together and letting you explore it in one elegant, unified interface. (Plus, we're sharing all the results in an API so you can come up with new ways to explore it.)
