Congress Swing Tracker is an independent, non-partisan political data tracker. We are not affiliated with, endorsed by, or connected to the United States Congress, the federal government, or any political campaign, party, or political action committee (PAC).

Legislative data, bill text, and voting records tracked on this platform are sourced from public government domains (including Congress.gov and GovInfo), along with other public datasets, including Voteview's roll-call and DW-NOMINATE data, and advocacy scorecards published by the League of Conservation Voters and Heritage Action for America. They are utilized for educational, informational, and analytical purposes.

The "Swing Scores" and lawmaker influence metrics displayed on this site are generated by our own algorithms and statistical models based on historical data, as documented on our Methodology page. These scores represent analytical estimates and projections only, not guarantees of future legislative outcomes or individual lawmaker behavior. Congress Swing Tracker accepts no liability for how these projections are interpreted or used by third parties.

Official lawmaker photographs and public domain assets are used for identification and informational purposes only. All trademarks, service marks, and logos referenced on this site are the property of their respective owners.
