Who shows up to vote?
A nonpartisan ranking of U.S. House members by roll-call attendance — every member measured against the same recent votes, so it’s a fair comparison.
Last updated: · Recomputed automatically as new roll calls are recorded.
Based on all 250 House roll-call votes recorded this year (rolls 34–283). Every member is measured against the same votes.
Method: for each recent House roll call we count how each member voted; “missed” means recorded as Not Voting. Non-voting territorial delegates and members without a near-full voting record are excluded, since they aren’t eligible for most floor votes. Source: Clerk of the U.S. House.
Who shows up in the Senate?
Based on all 231 Senate roll-call votes recorded this session. Every senator is measured against the same votes.
Source: U.S. Senate roll-call records. Senators are matched to votes by their Senate LIS identifier.
This data is free to use and cite, with no paywall and no attribution requirement beyond a link. It is compiled directly from official Clerk of the House and U.S. Senate roll-call records, and recomputed automatically. If you need the underlying vote-by-vote detail for any member, a custom breakdown, or a methodology walkthrough, ask — that is what it is here for.
ThePolitibase, "Congressional Attendance Leaderboard," accessed August 21, 2026. https://thepolitibase.com/leaderboards/Attendance is one of the few accountability measures that applies equally to every member — everyone faces the same roll-call votes. A missed vote means the member was recorded as Not Voting. Absences aren’t always avoidable (illness, family emergencies, official travel), so this is a factual record of participation, not a judgment.
