# United States Congress leaderboard method

## What this edition covers

This is a dated, source-linked snapshot of the 119th Congress. The underlying record contains all 441 House seat records in the frozen Clerk roster and all 100 current senators in the frozen congressional roster.

The public product publishes separate leaderboards for voting, lawmaking and collaboration. The House also has discharge-petition and community-project-request comparisons; the Senate has a sponsored-amendments comparison. Each table ranks one literal quantity. The quantities are never combined into an overall politician score.

## Who receives a rank

Members need a complete observation period before their figures can be compared fairly. The full-period group is determined from the voting data because it supplies an explicit shared-opportunity denominator:

- House members need records covering all 654 available House roll calls. This produces a 421-member ranking group.
- Senators need records covering all 890 available Senate roll calls. This produces a 95-member ranking group.
- Members who joined during the period remain in the underlying complete roster and can be viewed as partial-period context. They receive no leaderboard position.

The same full-period chamber group is used across that chamber’s published leaderboards. This prevents a member with a short record from leading a count or percentage through a much smaller opportunity window.

## How positions are assigned

Every published leaderboard uses these rules:

1. Sort the named quantity from highest to lowest.
2. Give equal values the same competition rank.
3. Skip the corresponding later positions after a tie. For example, equal first-place values are followed by third place.
4. Keep positions fixed when a reader filters by party or searches by name.

The main number and the rank are displayed separately. On voting pages, “654 of 654 eligible votes” explains the percentage while “Joint #1” states the leaderboard position. Currency tables show the number of requests underneath the dollar total.

## Publication bar

A measure becomes a leaderboard only when:

- a complete bounded roster exists;
- the quantity has the same literal definition for every ranked member;
- any necessary denominator is retained;
- stable official identifiers join members to records;
- the result can be reproduced from a frozen source snapshot;
- the comparison group has enough members and enough distinct values to form a useful list;
- the page can link readers to the relevant official record.

Sparse or structurally uneven measures stay out of the navigation. Enacted sponsored measures remain visible in the source data but are excluded because the values are too sparse for a useful standalone league. House amendments are also excluded; Senate amendments meet the current coverage and variation bar. Global committee attendance and office-cost tables remain excluded because the available records do not yet give every member a comparable opportunity and accounting period.

## Roll-call participation

The numerator is the number of Yea, Nay or Present records. The denominator is the number of roll calls in which the member appears in the chamber data. “Not voting” stays in the denominator and outside the numerator. The percentage is rounded to one decimal place.

The figure describes recorded floor voting. Pairing arrangements, illness, parental leave, official duties and other circumstances can affect it.

The separate **votes differing from the party majority** table considers only Yea-or-Nay votes. For each vote, the build identifies whether most voting Democrats and most voting Republicans voted Yea or Nay. It then reports the share on which a member voted the other way. Tied party positions, non-votes and independent members are not ranked in this comparison. The number describes a pattern; it is not a judgement about independence, loyalty or political courage.

House records come directly from the Clerk’s roll-call XML. Senate member votes and roll-call metadata use Voteview’s published transcription, with links to the corresponding official Senate roll call.

### Senate transcription audit

The audit sampled 12 evenly spaced roll calls from each session of the 119th Congress. Every sampled Voteview member cast was joined by normalized surname and state to the official Senate page, then the recorded categories were compared literally.

- 24 official roll calls checked;
- 2,399 individual senator-vote records checked;
- both sessions and the full available date span represented;
- zero mismatches.

The frozen audit is retained in the reproducibility bundle. The interface describes Voteview as a transcription checked against official records.

## Legislation leaderboards

The legislation archive contains every bill, joint resolution, concurrent resolution and simple resolution published by GovInfo for the 119th Congress at the snapshot date.

**Bills and joint resolutions sponsored** counts `HR`, `HJRES`, `S` and `SJRES` records for which the member is the official sponsor.

**Sponsored measures with recorded advancement** counts sponsored measures with at least one committee report, recorded vote or non-referral floor action in the official action history.

**Sponsored bills passed by their chamber** counts bills and joint resolutions carrying the official House- or Senate-passage action code for the sponsor’s chamber.

**Sponsored measures with cross-party co-sponsors** counts sponsored measures with at least one recorded co-sponsor from another party. Subject, scope and political significance vary by measure.

## Collaboration leaderboards

The collaboration category provides three different views of named Congress.gov records:

- **Measures cosponsored** counts proposals led by another member on which the person formally added their name.
- **Other-party measures cosponsored** retains only proposals whose lead sponsor was recorded in another party.
- **Other-party supporters attracted** counts individual other-party cosponsors on proposals led by the member.

These facts reveal visible patterns of support across Congress. They do not show how much drafting or negotiation a member did, and they do not evaluate the content of a proposal. The two cross-party views deliberately answer different questions: breadth of proposals supported and number of supporters attracted.

## House procedure and district-funding leaderboards

The **discharge petitions signed** table counts signatures published by the House Clerk across all 27 petitions in the frozen 119th-Congress register. A discharge petition is a specific attempt to bring a measure toward a floor decision without the usual committee route. The count is not a general activity or independence score.

The two fiscal year 2026 community-project tables use the House Appropriations Committee’s consolidated workbook of 5,414 requests:

- **requests** counts listed projects for each district;
- **amount requested** sums the listed dollar amounts.

The project title, recipient and amount remain available as item-level evidence. These are requests, not awards, obligations or spending. District needs and project costs differ, so larger values are not described as better.

## Senate amendments leaderboard

The same official BILLSTATUS archives contain amendments nested under their amended measure. The build deduplicates them by Congress, amendment type and amendment number.

- 7,036 unique amendment records found;
- 6,950 records contain a legislator BioGuide identifier;
- 86 committee-authored or otherwise non-person-attributed records are excluded;
- one duplicate occurrence is removed by the stable key;
- the archive contains 268 House amendments and 6,768 Senate amendments.

The public Senate table ranks the literal person-attributed count. Every expanded member row links to the underlying Congress.gov records.

## Current release decision

The USA leaderboard edition passes its local publication gates. It has a complete roster, multiple official record families, a declared full-period group, reproducible competition ranks and an audited Senate vote transcription. The House expansion adds two independent official families beyond roll calls and BILLSTATUS. Office spending, committee attendance, Congressional Record speaking counts and campaign-finance comparisons stay outside the leaderboard until they reach the same person-level completeness and audit standard.

Each figure describes a specific published record. Roles, opportunities and work outside Parliament or Congress also matter.
