A searchable database that presents some of the data with infographics.
The U.S. Congress Votes Database documents every vote and member of the House and Senate since 1991. Data is pulled from several sources, including the House clerk, the U.S. Senate and the Biographical Directory of the U.S. Congress. For the 112th Congress, users can analyze members and votes by various metrics, including caucus affiliations, 2010 margin of victory, and members endorsed by Tea Party Express or Freedom Works during the 2010 campaign. This site is a work in progress and will be expanded over time.
Here’s an example of a voting info page for Sen. Al Franken (D-MN) (112th Congress).
