AIPAC and Congressional Influence

For about sixty years, AIPAC did not give money to candidates.

That is worth stating clearly because it is the fact that makes everything after 2022 legible. The organization was enormously influential without writing checks. It built relationships with members and their staff, ran congressional trips to Israel, mobilized constituents, and coordinated a network of independent pro-Israel political action committees and donors who did the actual giving. AIPAC directed traffic. It was not the traffic.

Then it decided to be.

The 2022 change

Ahead of the 2022 midterms AIPAC created two new vehicles: a conventional political action committee and a super PAC called the United Democracy Project. For the first time it began spending directly on American elections.

The scale arrived quickly. Going into the 2024 cycle, with public argument over the war in Gaza intensifying, AIPAC announced it would spend $100 million through the two entities.

The giving is deliberately bipartisan, and the bipartisanship is the strategy rather than a softening of it. AIPAC PAC has given more than $3 million to party committees on both sides, including the National Republican Senatorial Committee, the Democratic Senatorial Campaign Committee and the Jeffries Majority Fund. Funding both parties is how you ensure that legislation passes regardless of which one is in charge.

What the money is for

The model runs on two incentives working together: support for members who cooperate, and expensive primary challenges against members who do not.

In 2024 that meant Jamaal Bowman and Cori Bush, two progressive House Democrats who had criticized Israeli policy in Gaza. AIPAC recruited and backed challengers against both. Both lost.

The Bowman race set the record at the time. According to the New York Times, AIPAC spent more on it than any interest group had ever spent on a single House race, roughly $14.5 million through the United Democracy Project.

That number is the message, and it is aimed at people who were not on the ballot. Every sitting member of Congress can read it. A statement critical of Israeli policy can summon spending that no individual campaign can hope to match.

Kentucky, 2026

Thomas Massie is a libertarian Republican who has refused AIPAC money and opposed American military aid to Israel. The 2026 primary in Kentucky’s fourth district became the most expensive House primary in the history of the United States.

Three political action committees tied to pro-Israel donors put more than $15.5 million into the race, according to Federal Election Commission filings. The United Democracy Project accounted for more than $4.1 million of it. The RJC Victory Fund, affiliated with the Republican Jewish Coalition, accounted for about $3.9 million. Total advertising spending in the primary passed $25 million, breaking the record the Bowman race had set two years earlier.

There is a detail in the Kentucky race that matters beyond the totals. The single largest spender was not any of the identified groups. It was a committee called MAGA KY, which spent $7.5 million and never fully disclosed its finances. The records that exist show one of its major funders was the investor Paul Singer, who was also the largest individual donor to the United Democracy Project over the preceding year at $2.5 million. MAGA KY also took money from Preserve America PAC, the committee associated with Miriam Adelson.

Reporting indicates this is a pattern rather than an accident. As scrutiny of AIPAC’s spending has grown, more of it has moved through intermediary committees whose donors are harder to follow, including a $1 million transfer to the 314 Action Fund in the 2024 cycle.

What AIPAC says

AIPAC describes itself as a bipartisan American organization advancing the American-Israeli relationship, funded by American citizens exercising First Amendment rights. On its account, its electoral spending is ordinary domestic political activity, no different in kind from that of any other advocacy group, and it is entirely lawful. That is correct as a matter of law. Nothing documented here is illegal.

The objection is not about legality. It is that spending concentrated specifically on removing members who criticize a particular foreign government functions differently from ordinary issue advocacy, and that the question of whether it should carry disclosure obligations is the one taken up in this archive’s case on foreign agent registration.

Why it matters

Something changed in 2022 that had held for six decades, and it changed in the direction of visibility, then immediately back toward opacity.

The mechanism is now on the public record and does not require anyone to infer it. Criticize Israeli policy and expect a funded primary challenge. The organization has demonstrated in three consecutive high-profile races that it has both the will and the money to make those challenges the most expensive in American history, and it distributes to both parties so that the outcome does not depend on which one wins.

The Kentucky race adds the newer development. The largest single expenditure in the most expensive House primary ever run came from a committee that never fully disclosed who funded it. An operation that spent sixty years working quietly, then six years spending openly, now appears to be moving back into the dark, and the reason is not hard to identify: the spending became visible enough to argue about.
