From the Sunlight Foundation Blog:
Open States is the only comprehensive database [it's also free to access and use] of activities from all state capitols that makes it easy to find your state lawmaker, review their votes, search for legislation, track bills and much more.
If you’re curious about a particular piece of legislation, Open States allows you to check on its status, find the sponsors, break down votes, view bill text and all supporting documents. Our powerful search capabilities allow you to find similar topics across states and view overview pages for each state, chamber and committee.
