A past Congress. The 118th Congress met from Jan. 3, 2023 to Jan. 3, 2025. Members are shown with the seat and party they held then; today's contact details, committees and caucuses aren't part of it.
118th Congress: sources and checks
This Congress's data was saved on Oct. 29, 2026 and doesn't change after that. Scores are computed from it the same way as the current Congress's (see “How we measure”). How we measure →
Voteview re-estimates DW-NOMINATE, the liberal-to-conservative scale, as new Congresses are added; the figures here are from the release downloaded on Oct. 29, 2026.
Checked against the official records
- House: 1,235 of 1,235 roll calls compared with the House Clerk's record of each one, member by member. All match. 19 of them elected the Speaker; those are compared by who voted, since the votes are names.
- Senate: 213 of 691 roll calls compared with the tallies Congress.gov's bill records print. All match. The Senate's own records couldn't be read automatically, and Congress.gov's bill records don't cover votes on nominations, so the other 478 weren't checked this way.
Votes with the President
Each member's score is the share of their votes that matched the President's public position, counted separately for each President, with missed votes left out. The positions follow the same rule as the current Congress's, set out on the main methodology page. Software matched the White House statements to votes, and every match was checked, with AI assistance (Claude) and no human editor, against the statement's text, the vote record and news coverage.

President Biden: 399 votes (228 nominations, 12 veto overrides, 150 White House statements on the bill, 9 other public statements). President's positions →
28 entries took a judgment call: a position applied to a procedural vote, a statement made more than 60 days before the vote, or a position added in the fact-check without a statement naming that exact vote. They're flagged on the positions page for sign-off by a named PCG editor, and they still count.
Voteview, the source of these roll calls, records the President's position on 318 of them. Of those, 314 agree with this site's list, 0 disagree and 4 have no position here.
Compared with CQ
CQ Roll Call publishes each year's average presidential support by party. The same average, computed here CQ's way (counting a member's missed votes against them), is shown beside it; the site's own scores leave missed votes out.
| Year | Chamber | Party | CQ | This site, CQ's way | Difference | Source |
|---|---|---|---|---|---|---|
| 2023 | Senate | Democrats | 95% | 94.7% | -0.3 | Roll Call, Feb. 15, 2024 (Niels Lesniewski and Ryan Kelly) |
| 2023 | Senate | Republicans | 18% | 17.6% | -0.4 | Roll Call, Feb. 24, 2025 (Niels Lesniewski and Ryan Kelly) |
| 2023 | House | Democrats | 95% | 93.7% | -1.3 | Roll Call, Feb. 15, 2024 (Niels Lesniewski and Ryan Kelly) |
| 2023 | House | Republicans | 5% | 3.3% | -1.7 | Roll Call, Feb. 15, 2024 (Niels Lesniewski and Ryan Kelly) |
| 2024 | Senate | Democrats | 95% | 94.1% | -0.9 | Roll Call, Feb. 24, 2025 (Niels Lesniewski and Ryan Kelly) |
| 2024 | Senate | Republicans | 25% | 23.7% | -1.3 | Roll Call, Feb. 24, 2025 (Niels Lesniewski and Ryan Kelly) |
| 2024 | House | Democrats | 88% | 88.9% | +0.9 | Roll Call, Feb. 24, 2025 (Niels Lesniewski and Ryan Kelly) |
| 2024 | House | Republicans | 19% | 14.8% | -4.2 | Roll Call, Feb. 24, 2025 (Niels Lesniewski and Ryan Kelly) |
CQ counted 72 House votes with a presidential position in 2024. The difference comes from votes where CQ found a White House position that this site's rule doesn't count: the January and February 2024 stopgap funding bills (H.R. 2872, H.R. 7463), on which the press secretary declined to take a position before the votes; the December 2024 defense bill (H.R. 5009), with no statement before the vote; and the June 2024 House defense bill (H.R. 8070), whose statement backed passing a defense bill in general while objecting to that one. Counted as Yes, those four votes would put House Republicans at 18.0 and House Democrats at 87.2.
Party loyalty for 2023–2024 isn't compared with CQ's party-unity averages; it's computed from Voteview's records the same way as the current Congress's.

Committees, member caucuses, contact details and district maps are today's, so they aren't shown here. Neither are presidential election results by district, so a member's score isn't compared with what their district's vote would predict.
