A past Congress. The 114th Congress met from Jan. 3, 2015 to Jan. 3, 2017. Members are shown with the seat and party they held then; today's contact details, committees and caucuses aren't part of it.
114th 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: 1,322 of 1,322 roll calls compared with the House Clerk's record of each one, member by member. All match. 2 of them elected the Speaker; those are compared by who voted, since the votes are names.
- Senate: 451 of 502 roll calls compared with the tallies Congress.gov's bill records print. 1 differ: 114-s129. 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 51 weren't checked this way.
For 114-s129 the Congressional Record and Senate Daily Digest give yeas 49, nays 48, as Voteview does; Congress.gov's bill record gives 48-48.
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 Obama: 237 votes (45 nominations, 3 veto overrides, 178 White House statements on the bill, 11 other public statements). President's positions →
34 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 237 of them. Of those, 199 agree with this site's list, 0 disagree and 38 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 |
|---|---|---|---|---|---|---|
| 2015 | House | Democrats | 87% | 84.7% | -2.3 | Brookings, Vital Statistics on Congress, table 8-2 |
| 2015 | House | Republicans | 13% | 13.8% | +0.8 | Brookings, Vital Statistics on Congress, table 8-2 |
| 2015 | Senate | Democrats | 88% | 88.4% | +0.4 | Brookings, Vital Statistics on Congress, table 8-2 |
| 2015 | Senate | Republicans | 59% | 53.5% | -5.5 | Brookings, Vital Statistics on Congress, table 8-2 |
| 2016 | House | Democrats | 92% | 88.2% | -3.8 | Brookings, Vital Statistics on Congress, table 8-2 |
| 2016 | House | Republicans | 8% | 9.2% | +1.2 | Brookings, Vital Statistics on Congress, table 8-2 |
| 2016 | Senate | Democrats | 86% | 84.9% | -1.1 | Brookings, Vital Statistics on Congress, table 8-2 |
| 2016 | Senate | Republicans | 48% | 53.4% | +5.4 | Brookings, Vital Statistics on Congress, table 8-2 |
These are Brookings's tables of CQ's scores; Roll Call's own party averages for 2015 and 2016 weren't found. They appear to leave missed votes out, though their notes say otherwise: counted that way here, 2015 Senate Republicans are 57.4 and 2016 House Democrats 92.4. The largest gap is 2016 Senate Republicans, 53.4 here (57.7 without missed votes): that year had few position votes, 27 here and 30 at CQ, so a few different votes move the average a lot; which ones differ isn't known. CQ counted 89 House and 75 Senate position votes in 2015 and 54 in the House in 2016; this site has 84, 59 and 67.
Party loyalty for 2015–2016 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.
