A past Congress. The 117th Congress met from Jan. 3, 2021 to Jan. 3, 2023. Members are shown with the seat and party they held then; today's contact details, committees and caucuses aren't part of it.
117th Congress: sources and checks
This Congress's data was saved on Oct. 30, 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. 30, 2026.
Checked against the official records
- House: 996 of 996 roll calls compared with the House Clerk's record of each one, member by member. All match. 1 of them elected the Speaker; those are compared by who voted, since the votes are names.
- Senate: 377 of 949 roll calls compared with the tallies Congress.gov's bill records print. 7 differ: 117-s52, 117-s54, 117-s73, 117-s815, 117-s852, 117-s853, 117-s883. 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 572 weren't checked this way.
Six differ by one vote, 50-50 here and 51-50 at Congress.gov: its tally includes the Vice President's tie-breaking vote, and Voteview's lists senators only.
Congress.gov's bill record gives 61-37 for 117-s883; the Congressional Record for Nov. 15, 2022 gives yeas 62, nays 36 (Rollcall 355), as Voteview does.
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. How we measure →
President Trump: 5 votes (0 nominations, 0 veto overrides, 0 White House statements on the bill, 5 other public statements). President's positions →
President Biden: 454 votes (290 nominations, 0 veto overrides, 153 White House statements on the bill, 11 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 463 of them. Of those, 453 agree with this site's list, 0 disagree and 10 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 |
|---|---|---|---|---|---|---|
| 2021 | House | Democrats | 99% | 99.1% | +0.1 | Roll Call, March 1, 2022 (Niels Lesniewski and Ryan Kelly) |
| 2021 | House | Republicans | 13% | 12.9% | -0.1 | Roll Call, March 1, 2022 (Niels Lesniewski and Ryan Kelly) |
| 2021 | Senate | Democrats | 97% | 97.0% | +0.0 | Roll Call, Feb. 24, 2025 (Niels Lesniewski and Ryan Kelly) |
| 2021 | Senate | Republicans | 29% | 27.1% | -1.9 | Brookings, Vital Statistics on Congress, table 8-2 |
| 2022 | House | Democrats | 99% | 98.9% | -0.1 | Roll Call, Feb. 24, 2025 (Niels Lesniewski and Ryan Kelly) |
| 2022 | House | Republicans | 19% | 17.9% | -1.1 | Brookings, Vital Statistics on Congress, table 8-2 |
| 2022 | Senate | Democrats | 95% | 95.2% | +0.2 | Roll Call, Feb. 24, 2025 (Niels Lesniewski and Ryan Kelly) |
| 2022 | Senate | Republicans | 24% | 24.3% | +0.3 | Roll Call, March 23, 2023 (Niels Lesniewski) |
Only Biden's positions are compared, as CQ's year is his; Trump's in January 2021 are shown separately. Brookings's figures for 2021 Senate Republicans and 2022 House Republicans appear to leave missed votes out: counted that way here, they're 29.4 and 18.8. CQ counted 55 House and 170 Senate position votes in 2021 and 66 House in 2022; this site has 52, 169 and 65.
Party loyalty for 2021–2022 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.
