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 170 House roll-call votes recorded this year (rolls 126–295). 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 crosses party lines?
On some votes the two parties line up against each other. 113 of the recent House roll calls below were votes like that. These boards count how often each member sided with their own party’s majority on those votes — and how often they didn’t.
Method: a “party vote” is a roll call where a majority of Democrats voted opposite a majority of Republicans — the standard Congressional Quarterly definition. Lopsided votes (naming a post office, honoring a team) are excluded, because nearly every member agrees on those and including them would score everyone above 95%. A member “broke with their party” when they voted the opposite way from their own caucus’s majority on one of those votes. Absences and Present votes are not counted either way. Members with fewer than 8 recorded party votes are not ranked. Independents are excluded, having no caucus line to cross. 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.

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 September 12, 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.
