The vote-by-vote record
This page shows the record in totals. Every individual vote Jon Tester has cast — how they voted on each measure, bucketed by measure family, with the bill attached — is in Elected Voting Records.
Open the full recordHow we build this
Member records, terms and vote counts come from Congress.gov and the Biographical Directory of the United States Congress. The portrait is the member's official Bioguide photograph. Every number on this page is a count of government records — nothing here is generated text.
Where a member is no longer in office we say so and link the source. We do not state why someone left: Congress.gov can prove death, and retirement, defeat, resignation and appointment elsewhere are indistinguishable in the record. We will not guess between them.
