Reach, side by side

Bars are scaled against all 537 members of Congress, so an organization's bar shows the share of the institution it reaches. Sector bars count members receiving money from any PAC in that sector.

What each organization's list rests on

Endorsement data has no bulk source; it was brought in, organization by organization, from published lists and reporting. These notes state plainly how complete each list is and what could not be verified, because an endorsement count is only as good as its coverage.

National Rifle Association Political Victory Fund 206 members

Source: NRA-PVF's own state-by-state candidate pages for the November 5, 2024 general election, retrieved via Wayback Machine snapshots taken Nov 2-3, 2024 (all 50 states captured; every page header confirms 'Election held on Tuesday, November 5, 2024'). The live nrapvf.org site is now behind an age-verification gate that was not bypassed, and no 2026-cycle NRA snapshots were retrievable, so ONLY the 2024 cycle is covered here. GRADE VS. ENDORSEMENT: NRA-PVF assigns every candidate a letter grade (A+, A, AQ, B, C, D, F, ?) and separately endorses a subset. Only candidates whose page entry carries the explicit NRA-PVF endorsement badge (markup class 'candidate-endorsed-true' plus an image with alt text 'NRA Endorsed') are included; a high grade alone was NOT treated as an endorsement. Across the 50 archived pages, 3,347 candidates at all levels of office carried the endorsement badge, of which 237 were U.S. House or U.S. Senate candidates; 206 of those 237 are currently serving in the 119th Congress and appear below. The other 30 lost their races or have since left Congress (e.g., Matt Gaetz, Mike Waltz, Mark Green, Marjorie Taylor Greene, Tony Gonzales-era vacancies) and were excluded. This should be close to complete for the 2024 cycle, but a handful of endorsements announced after the archive snapshot dates (Nov 2-3, 2024) would be missed. Cross-checked against Ballotpedia's independently sourced NRA-PVF endorsement list; all four of its 2024 congressional entries (Mike Bost, Ryan Mackenzie, Riley Moore, Jim Banks) appear below. Member identity and current service verified against the unitedstates/congress-legislators current roster.

U.S. Chamber of Commerce 98 members

Source: every endorsement press release published on the U.S. Chamber's own Elections page (uschamber.com/improving-government/elections), crawled exhaustively through all listing pages (214 unique announcements total, dated 2022-2026). Each entry below links to the individual Chamber press release announcing that endorsement. ENDORSEMENT VS. SCORECARD: the Chamber separately publishes a 'How They Voted' legislative scorecard and sends key-vote letters; none of that was used here. Only candidates named in an explicit 'U.S. Chamber Endorses...' press release are included. Scope: announcements from the 2024 cycle (91 current members), the 2025 FL-06 special election (1), and the 2026 cycle through July 22, 2026 (13) - 105 distinct current members. Roughly 81 additional 2022-cycle announcements exist on the same page but were excluded as too stale to represent current standing. Announcements for candidates who lost, or who have since left Congress (e.g., Lori Chavez-DeRemer, Brandon Williams, Marc Molinaro, Anthony D'Esposito, Tony Gonzales), were excluded. The 2026 cycle is still in progress, so that portion is necessarily incomplete as of July 22, 2026. Three entries are endorsements for a different seat than the member currently holds (Andy Barr and Julia Letlow are endorsed for U.S. Senate runs; Julie Johnson is endorsed for TX-33 under the new Texas map) - the 'district' field shows the seat they currently hold and the source_note explains the difference. Member identity and current service verified against the unitedstates/congress-legislators current roster.

American Federation of Labor and Congress of Industrial Organizations 47 members

PARTIAL SAMPLE, NOT A COMPLETE LIST. The national AFL-CIO does not publish a consolidated national roster of congressional endorsements. It endorses for president and delegates candidate endorsements to its 50-plus state federations and central labor councils, each running its own COPE convention and posting results separately, often only as PDFs, images, or member-login pages. The entries below come from the state federation sources that were retrievable (VA, IL, WA, CO, MN, FL, TX, MI, NY); the true national total is several hundred and is not publicly retrievable in one place. Treat this count as a floor. No member was added from an AFL-CIO scorecard rating, from PAC contributions, or by inference from party or voting record. Notable: the Florida AFL-CIO endorsed Republican Mario Diaz-Balart, and the Washington State Labor Council endorsed every incumbent Washington Democrat except Marie Gluesenkamp Perez. Several states redrew maps mid-decade, so a district printed in a 2026 source can differ from the member's current seat; district fields here are the member's current 119th Congress district.

Club for Growth 47 members

Built almost entirely from Club for Growth's own published endorsement and results pages, supplemented by named press releases and reputable news for older cycles. Includes only people seated in the 119th Congress, and only where an actual endorsement is documented. Club for Growth Foundation scorecard ratings, independent-expenditure spending, and Freedom Caucus membership were all deliberately excluded, since none of them is an endorsement. Editorial rule applied here: an endorsement counts when Club for Growth backed the member for a seat in Congress (House or Senate) in any cycle, including a 2026 Senate bid by a sitting House member. Endorsements for non-congressional office are recorded but not counted. Andy Biggs appears only as a 2026 Arizona gubernatorial endorsement and is therefore uncounted. Members endorsed for governor who also hold an earlier congressional endorsement (Tuberville, Blackburn, Donalds) are counted on the congressional one. Limitations: Club for Growth's 2020-and-earlier full lists are no longer published, so the 2020 set comes from their "Congratulates 2020 Election Winners" release and 2020 endorsees who lost that year but later returned to Congress may be missing; Ballotpedia's Club for Growth pages would not load for cross-checking. Absence from this list is not evidence of non-endorsement; several plausible senators and representatives could not be verified and were left out.

International Union, United Automobile, Aerospace and Agricultural Implement Workers of America 22 members

PARTIAL SAMPLE. The UAW's official endorsement portal is an address-lookup and state-map tool rather than a downloadable national list, and it prints no cycle label on its state pages; several state pages return 404 and others list only state and local races. Endorsements are also made independently by UAW Regions and by individual locals on separate sites, some of which returned HTTP 403. To guard against name and district misalignment in the source rendering, entries taken from the state-map pages were included only where the district printed in the source exactly matches the member's known current district. The portal's Ohio page pairs Joyce Beatty with a district number inconsistent with her current seat, so she is omitted here rather than risk a bad match. Much of the UAW's high-profile 2026 activity backed non-incumbent challengers, who are excluded. No member was added from the UAW's House and Senate scorecards or from UAW V-CAP contributions.

Working Families Party 22 members

Built from WFP's own site: the live 2026 endorsed-candidate roster and per-state pages, cross-checked against individual endorsement releases, plus WFP's official 2022 and 2024 post-election memos and its 2022 "Squad" endorsement post. Confidence is highest for the 2026 entries and for Ocasio-Cortez, Pressley, Omar and Tlaib (explicit "proud to endorse" language) and for Hayes, Vasquez and Ryan (WFP's 2024 memo calls them "WFP-endorsed incumbents"). Weaker but still documented on WFP's own site are Ramirez, Crockett, Balint, Frost and Salinas, where WFP describes them as champions it elected or "strongly backed" rather than publishing a standalone endorsement release; each is flagged in its source note. Could not verify and therefore omitted: 2024 New York WFP ballot-line cross-endorsements (Ballotpedia and the Internet Archive were both unfetchable, and the NY page now shows only the 2026 slate), so members who likely ran on the WFP line are missing. Also omitted: Rep. Tom Suozzi, whom the 2024 memo says WFP helped elect without claiming an endorsement, and Senators Baldwin, Gallego, Slotkin and Alsobrooks, who appear in that memo only as beneficiaries of WFP field programs. WFP's 2026 roster is still being released on a rolling basis, so this list will grow.

International Brotherhood of Teamsters 14 members

PARTIAL SAMPLE. The Teamsters endorse through state conferences, joint councils and locals rather than a single national list, and the International's own site carries only a handful of congressional endorsement releases. The entries below come from official Teamsters press releases and are unusually well documented, but they are not a complete national picture. Notable context: in September 2024 the International made no endorsement in the presidential race, the first time since 1996, and General President Sean O'Brien spoke at the 2024 Republican National Convention. The Ohio Conference of Teamsters' July 2026 slate endorsed five Republicans and five Democrats in U.S. House races, all incumbents, explicitly keyed to their votes for the Faster Labor Contracts Act, with the conference president stating the union does not care about party affiliation; the Pennsylvania Conference separately endorsed Republican Rob Bresnahan. Republican congressional endorsements by a major union are rare and are flagged in the entries below. No member was added from Teamsters DRIVE PAC contributions, scorecards, or voting records. Sherrod Brown was endorsed by the Ohio Conference for Senate but is not a sitting member and is excluded.

Our Revolution 11 members

Built by paging through Our Revolution's own endorsement archive and cross-checking against their master champions page; individual posts were spot-verified for the exact "Our Revolution is proud to endorse" language. Every entry below is a sitting 119th Congress member with a dedicated Our Revolution endorsement post. Significant limitation: the archive only reaches back to roughly May 2025, so endorsements from the 2024 cycle and earlier are not captured. Sitting members who are longtime Our Revolution allies but have no post in the current archive, including Rashida Tlaib, Bernie Sanders, Pramila Jayapal, Ayanna Pressley and Jesus "Chuy" Garcia, are deliberately omitted rather than assumed, so this count understates the organization's historical reach. Endorsement pages carry no visible publication dates, so cycle years are inferred from archive listing dates.

Service Employees International Union 11 members

PARTIAL SAMPLE, SUBSTANTIALLY INCOMPLETE. SEIU International does not publish a consolidated national congressional endorsement list; endorsements are made by state councils and large locals (32BJ, 1199SEIU, 1021, 521, UHW and others), each publishing separately. Several SEIU local endorsement pages returned HTTP 403 or published lists only as images and could not be verified. The true count is likely well over 100 Democrats, so treat the number here as a floor rather than a measurement. Every entry is an affiliate, local or state-council endorsement rather than an International endorsement, with the endorsing body named. No member was added from scorecard ratings or from SEIU COPE PAC contributions, since money is not an endorsement. 1199SEIU's April 2026 round was reported to include Rep. Adriano Espaillat, but the reporting was not explicit enough to verify, so he is omitted.

Justice Democrats 9 members

High confidence. Primary source is Justice Democrats' own candidates page, which groups nine sitting House members under "Current Congressmembers"; that list matches an independent April 2025 snapshot of the same page. All nine are additionally endorsed for their 2026 primaries; the cycle field records the ORIGINAL endorsement. Verified exclusions: Maxwell Frost is not a JD endorsee (absent from JD's list, and 2022 coverage counted Summer Lee and Greg Casar as JD's 11th and 12th wins while listing Frost separately). Cori Bush and Jamaal Bowman are JD endorsees but lost their 2024 primaries and are not current members. Raul Grijalva was a longtime endorsee but died in March 2025. Limitation: original-cycle attribution for Pressley, Omar and Jayapal rests on secondary coverage rather than a retrievable JD press release.

Sunrise Movement 8 members

Built from the Sunrise Movement's own endorsement index captured at multiple points in time, cross-checked against its live endorsement post list. Sunrise's full historical roster across 2018-2026 contains roughly 40 candidates; only the eight below currently serve in the 119th Congress. All pre-2026 individual endorsement pages have been deleted from the live site and now return HTTP 404, so sources point to Internet Archive captures of the official pages (the Markey page is still live). Cycle is taken from Sunrise's own cycle tags on each page. Deliberately excluded: Cori Bush and Jamaal Bowman, endorsed in 2020/2022/2024 but defeated in their 2024 primaries. Bernie Sanders was endorsed by Sunrise in January 2020 explicitly for President, not for his Senate seat, so he is not counted here. Sunrise's 2026 slate so far backs challengers to sitting Democrats rather than incumbents, with Markey the only sitting member re-endorsed. Local Sunrise hub endorsements are excluded as they are not national organization endorsements.

Democratic Socialists of America 2 members

Only two sitting members of the 119th Congress hold a currently-active DSA endorsement: Rashida Tlaib (national DSA plus Metro Detroit DSA) and Alexandria Ocasio-Cortez (NYC-DSA chapter only; the national endorsement was withdrawn in July 2024 and has not been reinstated). Explicitly checked and excluded for lack of any documented endorsement: Ilhan Omar, Delia Ramirez (affiliated with United Working Families, a different organization), Jesus "Chuy" Garcia, and Shri Thanedar (expelled former member, never endorsed). Cori Bush and Jamaal Bowman lost their 2024 primaries and are not current members. DSA-endorsed winners of 2026 primaries do not take office until January 2027 and are excluded. Limitation: dsausa.org, electoral.dsausa.org and ballotpedia.org all returned HTTP 403 to automated fetches, so DSA's own national roster was not read first-hand; national-DSA facts here rest on City & State New York, The Hill, and campaign sources. Entries below with a status other than "endorsed" are recorded to prevent them being mistakenly re-added later, and are not counted as endorsements.
