An independent, non-government record of how Congress votes Here’s how we know

Congress Vote Tracker is a private, independent project. It is not affiliated with the U.S. government, Congress, or any agency, and it does not speak for them. Every vote count is drawn from official public records (Congress.gov, the House Clerk, and Senate.gov) and linked back to the source on every page.

About Congress Vote Tracker

Independent civic journalism. Every vote on record. No spin.

Our Mission

Congress Vote Tracker monitors every recorded vote in the U.S. House of Representatives and Senate, scores legislators on party loyalty, attendance, and bipartisanship, and connects voting records to campaign finance data.

Our goal is simple: give citizens a clear, factual record of how their representatives actually vote, not what they say on TV.

Editorial Standards

Vote breakdowns and bill summaries are presented as neutral data journalism. We report the numbers. Analysis pieces are clearly labeled [ANALYSIS] and may include editorial perspective: those are opinions, not facts, and are clearly distinguished.

We do not engage in partisan cheerleading. We hold all elected officials to the same standard: their actual voting record.

Data Sources

All data is sourced from public records and official APIs:

  • Congress.gov · Official bill text, roll call votes, member records
  • Congress.gov API · House roll call votes, bill and member metadata (updated automatically each day)
  • Office of the Clerk, U.S. House · Official House roll call vote records
  • U.S. Senate · Official Senate roll call vote records
  • GovTrack · Historical voting records and ideology scores
  • OpenSecrets · Campaign finance and lobbying data
  • Public congressional records and press releases

Every voting data point links to the source roll call page on Congress.gov. Every bill reference links to the official bill text. Dead links are removed before publication.
