Tensions within the Democratic Party over the role of the American Israel Public Affairs Committee have intensified ahead of the 2026 midterm elections, with several progressive challengers openly campaigning against the group’s spending and policy influence. As of May 2026, the disputes have produced mixed primary results and deepened broader debates within the party over campaign finance and its direction on Middle East policy.
Support for Israel has historically been bipartisan in American politics, but polling shows declining unconditional backing among Democratic voters, particularly younger and more progressive ones, amid the ongoing conflict in Gaza and broader regional tensions, including the crisis involving Iran. A growing number of Democratic voters now favor conditioning U.S. military aid to Israel or placing greater emphasis on Palestinian rights and a two-state solution.
AIPAC and affiliated super PACs, including the United Democracy Project, continue to spend heavily to support candidates who back strong U.S.-Israel security cooperation. Critics argue this outside spending distorts primary races and pressures candidates into adopting positions misaligned with their districts’ actual views. Supporters counter that the organization is defending a critical strategic alliance for the United States.
The financial stakes of these primary battles have been substantial. In Illinois, AIPAC-linked groups spent more than $20 million during March 2026 primaries, producing a split outcome. Evanston Mayor Daniel Biss won an open seat after making opposition to AIPAC a central theme of his campaign, even as several AIPAC-backed candidates won in other districts across the state.
Similar dynamics have played out elsewhere. In Michigan, Dr. Abdul El-Sayed is challenging Rep. Haley Stevens, criticizing her ties to AIPAC and calling for an end to unconditional U.S. aid to Israel. In New Jersey, progressive candidate Analilia Mejia secured an upset victory in a special election after running on similar themes. Progressive organizations such as Justice Democrats have endorsed dozens of candidates nationwide who have pledged to reject money from pro-Israel political action committees.
The scale and structure of AIPAC-affiliated spending have drawn particular scrutiny. The group’s super PACs have often deployed funds through vehicles framed around local issues rather than foreign policy directly, prompting criticism from opponents who point to the use of so-called dark money in these races.
Defenders of AIPAC note that progressive groups also spend significant sums in primary contests, and that all spending activity complies with federal disclosure requirements.
The broader conflict has exposed deeper fault lines within the Democratic coalition. Establishment-aligned Democrats worry that aggressive anti-AIPAC positioning could alienate moderate voters, Jewish communities, and major donors who have traditionally supported the party. Progressives, meanwhile, view confronting the group’s influence as essential to reflecting shifting voter priorities and reducing the outsized role of single-issue lobbying groups in shaping policy.
These tensions arrive as public opinion among Democrats continues to evolve, particularly among younger voters who have grown more skeptical of unconditional support for Israel. How the party manages the resulting internal divisions could have significant implications for unity heading into the November midterm elections.
