The measurable impact on progressive voices in the Democratic party runs through one channel the public record captures, primary spending, and it is documented to the dollar rather than inferred. The United Democracy Project, the super PAC affiliated with the American Israel Public Affairs Committee, reported $37,860,200 in independent expenditures in the 2023-2024 cycle, and the filings record $20,786,780 of it spent opposing Democratic candidates against $14,067,863 supporting them, per OpenSecrets’ tabulation of Federal Election Commission filings. What that money is recorded as doing to those voices, and what it is not, are two different questions, and only one of them has an answer in the filings. More than $14.6 million of that cycle’s spending went into a single House primary, New York’s 16th District. Across the same period, the recorded votes on Israel security assistance passed the House 420 to 9 in September 2021 and 366 to 58 in April 2024, with 37 of the 58 no votes cast by Democrats.
Key Findings
- The United Democracy Project reported $37,860,200 in independent expenditures for the 2023-2024 cycle: $20,786,780 opposing Democrats, $14,067,863 supporting Democrats, $3,043,662 opposing Republicans and $0 supporting Republicans, per OpenSecrets’ tabulation of FEC filings.
- AIPAC’s connected PAC, FEC committee C00797670, gave $3,037,900 directly to federal candidates in the same cycle, 36.62% of that total to Democrats and 63.02% to Republicans, spread across 347 House and 20 Senate candidates, with a largest single recipient total of $20,000 (OpenSecrets, 2025).
- On the recorded votes, the House passed the $1 billion Iron Dome supplemental 420 to 9 on 23 September 2021 (Roll Call 275) and the Israel security supplemental 366 to 58 on 20 April 2024 (Roll Call 152, Republicans 193 to 21, Democrats 173 to 37), per congress.gov.
- Gallup’s February 2023 reading recorded Democrats sympathizing more with the Palestinians (49%) than the Israelis (38%) for the first time in the trend; by February 2025, 46% of all US adults sympathized more with the Israelis, the lowest reading in 25 years (n = 1,004, ±4 points).
- About 62% of the antisemitic tweets referencing Jews in the 4,016-tweet expert-annotated corpus of Jikeli and colleagues (2022, peer-reviewed) fit the IHRA paragraph on mendacious or stereotypical allegations about Jewish collective power.
What does the spending record show against progressive Democrats?
The filings record $20,786,780 spent opposing Democratic candidates by the United Democracy Project in the 2023-2024 cycle, against $14,067,863 supporting Democratic candidates, out of $37,860,200 in total reported independent expenditures, per OpenSecrets’ tabulation of FEC filings.
The same filings record $3,043,662 opposing Republicans and $0 supporting them. Those four directional figures sum to $37,898,305, about $38,105 above the $37,860,200 the same tabulation reports as the cycle total, so the categories and the total are not two views of one number and are not presented here as reconciling.
The second, smaller channel is direct giving. AIPAC’s connected PAC, FEC committee C00797670, contributed $3,037,900 to federal candidates in the 2023-2024 cycle, 36.62% of that total to Democrats and 63.02% to Republicans, reaching 347 House candidates and 20 Senate candidates, per OpenSecrets’ tabulation of the committee’s filings. The largest single recipient total in that channel was $20,000 (Ronny Jackson, R-Texas), because a multicandidate committee’s direct contributions are capped at $5,000 per candidate per election under 52 U.S.C. 30116.
The two channels are not the same instrument, and the gap between them is the whole reason the independent-expenditure route matters in a primary. A capped $5,000 contribution goes to a campaign; an independent expenditure is, by the statutory definition that permits it to be uncapped, uncoordinated with any campaign. It is money spent about a race rather than given to a candidate, which is how a single committee’s reported spending in one cycle reaches twelve times the total of everything it gave directly.
What the filings establish is direction and amount. They record who was opposed, who was supported, and to the dollar how much, in itemized reports filed with a federal agency. They do not record effect, and the recipients counted in the direct channel are candidates rather than sitting members, so the 347 House figure is not a count of the chamber.
Is it often said the spending silences progressive critics?
It is often said that this spending makes criticism of Israeli government policy costly enough that Democratic candidates soften their positions to avoid becoming a target. The spending itself is documented and concentrated: more than $14.6 million, over a third of the United Democracy Project’s $37,860,200 cycle total, was reported in one House race, New York’s 16th District in 2024, per OpenSecrets’ tabulation of FEC filings.
Concentration is the load-bearing fact about the shape of the money. A committee that puts more than a third of a cycle’s reported independent expenditures into one of 435 contested House districts is not distributing pressure evenly across a party’s candidates; it is spending heavily in a small number of races. The filings support the first half of the common claim, that the money is large and that most of the reported Democratic-directed total was spent against rather than for Democratic candidates.
What the filings cannot supply is the second half, the inference about candidate behaviour, and the countervailing mobilization is measurable in a way the inference is not. Reuters reported on 7 May 2026 that groups organized against AIPAC had endorsed more than 100 Democratic candidates by 2026, in reporting on tensions over the organization inside Democratic primaries. That is a count of endorsements by named groups, not a count of positions changed, but it establishes that opposition to the spending had itself become an organizing category with more than a hundred endorsed candidates attached to it.
Both figures describe terrain rather than outcomes. One committee’s reported spending, concentrated in a handful of primaries, and more than a hundred candidates endorsed by groups organized in opposition to it, are the two sides of the same contest as the filings and the reporting record them.
Did the targeted progressive incumbents keep their seats?
The federal filings answer this question in one dimension only. They record that more than $14.6 million flowed into New York’s 16th District in the 2024 cycle, the largest single-race total in the United Democracy Project’s reporting for that cycle, per OpenSecrets’ tabulation of FEC filings, and they record the direction of every itemized expenditure.
They do not record results. An independent-expenditure report is a disclosure of money spent about a race, filed with the Federal Election Commission under the statutory definition that makes such spending uncoordinated with any campaign. Nothing in the filing measures vote share, turnout, or the counterfactual, and no source drawn on here publishes a rate at which targeted incumbents held or lost their seats. That absence is a feature of what campaign-finance disclosure is built to capture, not a gap in a particular filing.
The one recorded measure of whether dissenting positions survived in the chamber is the roll call. On 20 April 2024, after the 2022 and 2024 spending cycles, 37 House Democrats voted against H.R. 8034, the Israel Security Supplemental Appropriations Act, 2024, on a 366 to 58 passage vote (Roll Call 152 of the 118th Congress, per congress.gov). In the Senate the following day, 18 senators voted against H.R. 815, the national security supplemental carrying Israel, Ukraine and Indo-Pacific assistance, which was agreed 79 to 18 (Record Vote 154).
Those numbers describe the composition of a chamber after an election, not the fate of any individual candidate, and a roll call cannot separate members who were spent against from members who were not. Read together, the filings give the money by race and the votes give the dissent by count, and neither series measures the other.
Did the targeted progressives change their recorded votes?
The four recent recorded votes where Israel security assistance was the measure or its principal component show near-unanimous passage twice. On 23 September 2021 the House passed H.R. 5323, the $1 billion Iron Dome Supplemental Appropriations Act, 420 to 9 with 2 members voting present (Roll Call 275 of the 117th Congress, per congress.gov).
The margins move, and what moves them is legislative packaging rather than the assistance. H.R. 6126, the Israel Security Supplemental Appropriations Act, 2024, paired with a rescission of IRS funding as its offset, passed the House 226 to 196 on 2 November 2023, near party lines (Roll Call 577). H.R. 8034, essentially the same Israel assistance without the offset, passed 366 to 58 on 20 April 2024 (Roll Call 152), with Republicans voting 193 to 21 and Democrats 173 to 37. The two votes on comparable assistance differ by 140 House votes, and the variable between them is the offset.
The base rate constrains what any claim about a subgroup of members can mean. With only 9 members voting no on Roll Call 275, any subgroup of 100 members voted at least 91% yes on that measure, and any subgroup of 300 at least 97%, arithmetic that holds regardless of how the subgroup is defined. Near-unanimity in the chamber leaves very little room for a distinctive voting pattern among any set of members to appear.
Assistance is ordinarily carried inside the annual State, Foreign Operations appropriations act, where a vote on the package is not a vote on one line, which is why this four-vote set is the usable series. The Congressional Research Service records in RL33222 that Israel is the largest cumulative recipient of US assistance since the Second World War, at $174 billion in current dollars, and that Congress appropriated $8.7 billion in combined Foreign Military Financing and missile defense funding in FY2024.
How many candidates now refuse this money outright?
Reuters reported on 7 May 2026 that groups organized against AIPAC had endorsed more than 100 Democratic candidates by 2026, in reporting on tensions over the organization inside Democratic primaries. That is a count of endorsements issued by named opposition groups, and it is the largest specific number in the public record on the question.
An endorsement count and a refusal count are different quantities. No source drawn on here publishes a tally of Democratic candidates who pledged not to accept the organization’s contributions, and the disclosure system does not produce one: FEC filings record money received, so a candidate who took nothing is indistinguishable in the record from a candidate no committee approached.
What the filings do record is where the direct-contribution channel went. Of the $3,037,900 that AIPAC’s connected PAC gave federal candidates in the 2023-2024 cycle, 36.62% of that total went to Democrats and 63.02% to Republicans, reaching 347 House and 20 Senate candidates, per OpenSecrets’ tabulation. Track AIPAC, an advocacy tracker, counts 80 current members of Congress, 15% of the body, with AIPAC as their all-time top contributor on OpenSecrets data; that is the tracker’s own count on its own criteria.
So the measurable picture is a majority-Republican direct channel, a Democratic-directed independent-expenditure channel that ran more against than for, and more than a hundred Democratic candidates endorsed by groups organized in opposition. Whether any of those candidates would have accepted the money is not in the record.
Has the lobby become a litmus test in primaries?
Gallup’s February 2023 reading recorded Democrats sympathizing more with the Palestinians (49%) than with the Israelis (38%) for the first time in the trend, on the forced-choice question the organization has asked on its annual World Affairs survey since 1988.
By February 2025, Republicans stood at 75% sympathizing more with the Israelis and Democrats at 59% sympathizing more with the Palestinians.
The national trend moved with the partisan one. The 46% of US adults sympathizing more with the Israelis in February 2025 was the lowest reading in 25 years of the trend, against 63% in February 2010, and the 33% sympathizing more with the Palestinians was the highest by two points (n = 1,004, ±4 points). In the same 2025 survey, 55% of US adults favored establishing an independent Palestinian state, in line with readings since 2020.
Two caveats travel with these numbers. The question is a forced choice between two named parties, so it measures relative sympathy and not any view on assistance, conditions, or campaign spending. Gallup’s own 2018 methodology article documents that the question’s placement within a survey changes the shares it produces, which bears on comparisons across readings.
The Institute for National Security Studies, an Israeli research institute in Tel Aviv, published an analysis in 2025 titled “U.S.-Israel Alliance as a Litmus Test: The Democratic Primaries,” treating the alliance question as a dividing line in Democratic primary contests. Set beside the Gallup series, the sequence is legible: the attitudinal gap between the two parties’ voters widened first and is measured on a national instrument, while the primary spending is measured in filings, and no source drawn on here measures which of the two moved the other.
Can self-censorship by candidates actually be measured?
One peer-reviewed study measures congressional behaviour against disclosed contributions, and what it measures is bill sponsorship. Küçük (2025), in the Turkish Journal of Middle Eastern Studies, found that members who sponsor pro-Israel bills receive more campaign contributions, and that members facing stronger electoral competition attract more targeted donations.
The design’s limits are the point. It is correlational, and it cannot separate contributions that follow a position already held from contributions that shape one. Sponsorship is also a different act from voting: it is a voluntary individual initiative with a different base rate from a scheduled roll call, so a finding about one does not transfer to the other, and the near-unanimous margins on the recorded assistance votes leave little variance for either to explain.
No measured study identified here examines the behaviours the common claim actually describes: the wording a candidate chooses on the stump, which issues a campaign foregrounds, or a decision not to enter a race at all. Those are the mechanisms most often asserted, and the record contains statements by candidates about them rather than measurement of them. The absence is recorded here as the state of the evidence.
A second disclosed channel is gifted travel. The Guardian, analysing congressional ethics filings on 2 June 2026, tabulated that since 7 October 2023 at least 26 Democratic and 52 Republican representatives attended trips sponsored by the American Israel Education Foundation, AIPAC’s 501(c)(3) charitable affiliate, across at least 15 delegations, at more than $4.2 million in total and averaging over $26,600 per member. The underlying records are pre-travel approvals held by the House Committee on Ethics and post-travel disclosures filed with the Clerk. Under the 2007 travel rules, a lobbying organization may generally sponsor only single-day travel while a 501(c)(3) may sponsor longer trips; the foundation states its missions are educational.
Like the expenditure filings, the travel disclosures record a transaction and its value. They do not record a position taken afterward.
How does lobby-money framing appear in measured antisemitic content?
About 62% of the antisemitic tweets referencing Jews in the expert-annotated corpus of Jikeli and colleagues (2022, peer-reviewed) fit the IHRA paragraph on mendacious or stereotypical allegations about Jewish collective power, in a 4,016-tweet gold-standard sample of English-language tweets from January 2019 to August 2020. A further 15% fit denial of Jewish self-determination.
Becker, Ascone and Troschke (2022, peer-reviewed) coded 4,500 comments on the Facebook pages of leading British, French and German media outlets reacting to the May 2021 escalation, and found 26.9% of the 1,504 UK comments antisemitic against 12.6% of 1,500 French and 13.6% of 1,520 German comments. Within the UK antisemitic comments, the categories were led by an “evil” stereotype at 39.8% and Israel’s sole guilt at 27.9%, with the apartheid analogy at 5.2%. Thread context was needed to infer the antisemitic meaning in 38.7% of the UK cases.
On attitudes, Hersh and Royden (2022, peer-reviewed) ran experiments inside an original survey of about 3,500 US adults and found overt antisemitic attitudes rare on the political left and more common on the right, with the highest concentration among young adults on the far right. The Yale Youth Poll’s Fall 2025 national survey of registered voters found two-thirds rejecting all three antisemitic statements tested, including that Jews have too much power, while 10% of voters aged 18 to 34 agreed with all three against 2% of voters 65 and older.
These corpora measure the vocabulary of collective-power and influence claims and the prevalence of the underlying attitudes. None of the studies cited here coded statements about AIPAC, campaign finance, or any named organization, so the relationship between the two bodies of evidence in this report is one of shared vocabulary as measured in separate samples, and nothing in either measures the other.
Methodology and limitations
This report draws on five source types, each measuring something different. The campaign-finance figures are FEC independent-expenditure and contribution filings as tabulated by OpenSecrets (2025), based on FEC data released 6 February 2025 for the 2023-2024 cycle; filings record the direction and dollar amount of spending, never its effect. The vote figures are recorded votes published at congress.gov: House Roll Calls 275 (117th Congress), 577 and 152 (118th), and Senate Record Vote 154. The aid totals are from the Congressional Research Service report RL33222, a nonpartisan report to Congress whose figures move by edition, so the edition year travels with any total.
The public-opinion figures are Gallup’s forced-choice Middle East sympathies trend, with sample sizes and margins stated at each reading (n = 1,025 in February 2010, n = 1,004 in February 2025, ±4 points each). Gallup’s own 2018 methodology article documents that this question’s placement within a survey changes the shares it produces. The content and attitude figures come from peer-reviewed research: Jikeli and colleagues (2022) on an expert-annotated IHRA-based tweet corpus, Becker, Ascone and Troschke (2022) on coded Facebook comments, Hersh and Royden (2022) on survey experiments, and the Yale Youth Poll (2025) as an academic poll of registered voters. Becker’s category shares are non-exclusive and are shares of the antisemitic comments within each national sample, not of all comments.
Two figures are named tabulations by news organizations of primary filings, and are attributed to the outlet rather than to the filings: Reuters (7 May 2026) on the number of Democratic candidates endorsed by groups organized against AIPAC, and the Guardian (2 June 2026) on congressional travel sponsored by the American Israel Education Foundation, drawn from House ethics disclosures. The Institute for National Security Studies analysis (2025) is an Israeli research-institute publication, labelled as such.
Two absences shape what can be concluded. No source drawn on here publishes a rate at which candidates targeted by independent expenditures held or lost their seats, and campaign-finance disclosure is not built to produce one. No measured study identified here examines candidate messaging, issue selection, or decisions not to enter a race, which are the behaviours the common claim describes. Küçük (2025) is the closest measurement, and it measures bill sponsorship rather than roll-call voting, correlationally, without separating contributions that follow a position from contributions that precede one.
Conclusion
So what does the record hold when the question is how this spending lands on progressive Democrats? It holds the money in detail and the mechanism not at all. The United Democracy Project’s $37,860,200 in reported 2023-2024 independent expenditures, $20,786,780 of it against Democratic candidates and more than $14.6 million in one district, is itemized to the dollar in federal filings. Alongside it sits a capped direct channel of $3,037,900 that went 63.02% to Republicans, more than a hundred Democratic candidates endorsed by groups organized in opposition, and roll calls on which 37 House Democrats and 18 senators voted no in April 2024 after two cycles of that spending.
The attitudinal ground moved on its own instrument and on its own timetable, with Gallup recording Democrats crossing to majority Palestinian sympathy in February 2023 and national sympathy with the Israelis at 46% in February 2025, its lowest in 25 years. Sponsorship correlates with contributions in Küçük’s 2025 measurement; near-unanimous margins of 420 to 9 and 366 to 58 leave almost no variance for a subgroup pattern to occupy; and the one behaviour most often described, a candidate quietly choosing different words, has no measured study behind it at all.
That gap is where the Institute’s other measurement becomes uncomfortable. In the annotated corpora, about 62% of antisemitic tweets referencing Jews fit the IHRA clause on allegations of Jewish collective power, and 39.8% of antisemitic UK comments carried an evil stereotype. The vocabulary of hidden influence over legislatures is the most measured antisemitic vocabulary there is, and the subject of this report is a lawful, disclosed, itemized lobbying operation whose figures live in filings any reader can open. Two things share a vocabulary and differ entirely in what stands behind them. Which of those two a given claim about influence is actually reaching for, and how a reader is supposed to tell them apart when the filings say one thing and the trope says another, is the question this evidence puts in front of anyone who reads it.
Frequently Asked Questions
How large is US security assistance to Israel overall?
The Congressional Research Service records in RL33222 that Israel is the largest cumulative recipient of US bilateral assistance and missile defense funding since the Second World War, at $174 billion in current dollars, and that Congress appropriated $8.7 billion in combined Foreign Military Financing and missile defense funding in FY2024. Figures in that report move by edition, so any total should carry its edition year.
Where do the annual funding levels come from?
The 2016 Memorandum of Understanding between the United States and Israel on Security Assistance, signed at Washington on 14 September 2016, sets a ten-year framework of $38 billion for FY2019 to FY2028: $33 billion in Foreign Military Financing plus $5 billion in missile defense appropriations, per the Congressional Research Service. The memorandum’s own text states the levels are “subject to the appropriation and availability of funds,” so it sets a schedule rather than obligating money.
Why can a super PAC spend more than a PAC may contribute?
A multicandidate committee’s direct contributions are capped at $5,000 per candidate per election under 52 U.S.C. 30116, which is why AIPAC’s connected PAC gave 347 House candidates a total of $3,037,900 with a largest single recipient total of $20,000 (OpenSecrets, 2025). Independent expenditures are uncapped because, by the statutory definition that permits them, they are uncoordinated with any campaign.
Which records document gifted congressional travel?
Pre-travel approvals are held by the House Committee on Ethics and post-travel disclosures are filed with the Clerk of the House. The Guardian’s 2 June 2026 analysis of those filings tabulated at least 26 Democratic and 52 Republican representatives on American Israel Education Foundation trips since 7 October 2023, at more than $4.2 million in total.
How do researchers measure antisemitism in online text?
Jikeli and colleagues (2022) built an expert-annotated gold-standard corpus of 4,016 English-language tweets coded against the IHRA definition and found 23.1% antisemitic across the full corpus. Zannettou and colleagues (2020) took a different approach on over 100 million posts, judging 42% of random 100-post samples containing the word “jew” on two web communities to be hateful.
Why do incident counts and survey shares not line up?
They measure different universes. Monitoring organizations tally incidents reported to them on their own definitions, while surveys such as the Yale Youth Poll (2025) measure the share of a sampled population agreeing with a stated proposition, which is why that poll can record two-thirds of registered voters rejecting all three tested statements in the same period that incident tallies rise.
Does public opinion track the recorded votes?
Not closely, on the available series. Gallup recorded 46% of US adults sympathizing more with the Israelis in February 2025, the lowest reading in 25 years, and 55% favoring an independent Palestinian state, while the closest recorded votes on assistance passed 366 to 58 in the House and 79 to 18 in the Senate in April 2024.
