Overview
In Democratic primary fields across the country, a notable number of challengers have placed opposition to the American Israel Public Affairs Committee, commonly known as AIPAC, at the center of their campaigns. These primary fights are happening as policy disputes over the wars in Gaza and tensions with Iran intensify intraparty disagreements and influence the selection of nominees for November’s midterm election.
AIPAC, established in the 1950s, has long been one of Washington’s most prominent foreign-policy lobbying organizations. The group has spent millions to support candidates who favor a robust U.S.-Israel relationship, pushing for continued military assistance to Israel, sanctions on Iran, and other legislation it views as strengthening Israeli security. That established role is now drawing sustained scrutiny from insurgent Democrats who criticize the organization’s political spending and policy priorities.
Anti-AIPAC Mobilization
Two organizations leading the charge against AIPAC in Democratic primaries are Track AIPAC, which monitors AIPAC’s political expenditures, and Justice Democrats, a progressive political action committee. Together they have endorsed more than 100 Democratic candidates who have pledged to reject donations from pro-Israel groups, including AIPAC, and in many cases to oppose U.S. military aid to Israel.
According to a review of candidate questionnaire responses, of the 102 candidates endorsed by these anti-AIPAC groups, 73 are running against sitting Democratic members of Congress who have received support from AIPAC and allied pro-Israel groups. That dynamic signals a deliberate effort by these endorsing organizations to displace incumbents they view as aligned with entrenched pro-Israel influence.
Representatives of the organizations and their endorsed candidates contend that campaign finance ties and advocacy from AIPAC have shaped congressional positions on Israel and related conflicts. Critics among the challengers have mounted direct allegations, including accusations that AIPAC-backed policies have contributed to severe civilian harm in Gaza and that support for an expanded conflict with Iran is improper. AIPAC and its allies reject those accusations.
Responses from AIPAC and Established Democrats
An AIPAC spokeswoman, Deryn Sousa, said the organization is proud to help the mainstream of the Democratic Party and to keep what it described as far-left, anti-Israel fringe candidates from winning office. Sousa affirmed that AIPAC and its millions of Democratic supporters will remain active this cycle and in future cycles to elect candidates who back a strong U.S.-Israel partnership. She also blamed intraparty tensions on what she characterized as efforts to push pro-Israel Democrats out of the party.
Mainstream Democratic defenders of AIPAC emphasize national security rationales, bipartisan practice and electoral calculations in supporting candidates in competitive districts. Progressive and moderate factions within the party, however, remain divided over the extent of U.S. backing for Israel’s security measures.
Reflecting a sharp shift in public attitudes among Democratic voters and Democratic-leaning independents, a nonpartisan survey conducted in March by the Pew Research Center found roughly 80% of that group held an unfavorable view of Israel. That broad dissatisfaction among Democratic-aligned voters is a contributing factor to the vigor of these primary challenges.
Money, Endorsements and Electoral Stakes
OpenSecrets, a nonpartisan tracker of political spending, reported that AIPAC and its supporters provided nearly $25 million to Democratic congressional candidates ahead of the 2024 election cycle and more than $16 million to Republicans. Those figures underscore AIPAC’s financial reach across both parties.
Track AIPAC says its endorsements this year represent roughly an eightfold increase compared with two years ago. The group previously endorsed 12 Democratic candidates ahead of the 2024 election cycle. Justice Democrats, which did not endorse new primary challengers two years ago, has endorsed 15 new challengers this cycle: nine against sitting Democrats and six in open-seat contests.
The list of endorsed challengers includes two candidates contesting U.S. Senate seats in Maine and Michigan. Both Senate contenders are critics of Israel and AIPAC and are running competitive campaigns in races that could influence control of the Senate.
Prominent Races and Specific Allegations
Some primary matchups have produced sharp public accusations. Darializa Avila Chevalier, who is challenging Representative Adriano Espaillat of New York, has accused AIPAC of pushing representatives to be complicit in what she described as genocide in Gaza and of steering the United States toward a war with Iran. According to an OpenSecrets analysis of Federal Election Commission filings, Espaillat received over $133,000 from AIPAC and its supporters this election cycle and took $181,000 in the 2024 election.
Espaillat’s campaign spokesman, Reginald Johnson, said the congressman supports Israel’s right to exist as well as a Palestinian state, and opposes Israeli Prime Minister Benjamin Netanyahu’s expansion of military operations and the Iran war. That combination of positions illustrates the nuanced stances some incumbent Democrats have adopted in response to criticism from the left.
Intraparty Tensions Become Visible
Rifts over AIPAC and Israel demonstrated themselves at a Michigan Democratic convention on April 19, where a contentious primary for the party’s U.S. Senate nomination was underway. As Representative Haley Stevens, who is one of the Senate candidates, took the stage, parts of the audience booed and heckled her. Stevens has received over $220,000 from AIPAC and its supporters in this election cycle, according to OpenSecrets.
Video footage of the convention shows some attendees standing and chanting “Shame on you” as Stevens left the stage. A Stevens campaign spokesperson, Arik Wolk, said the congresswoman welcomed the ceasefire in Gaza that began last October and that she supports peace in the region. The ceasefire has been fragile and punctuated by intermittent outbreaks of violence.
Former Democratic congressman Steve Israel, who previously led the Democratic Congressional Campaign Committee, described these clashes as symptomatic of a broader shift inside the party. He said younger activists moving into party infrastructure and elected office are energizing the party further to the left, creating proxy battles such as whether a candidate will accept AIPAC support. Israel called such fights self-defeating litmus tests.
The Democratic National Committee did not directly address questions about tensions over AIPAC when contacted for comment.
Potential Electoral Consequences and Political Calculations
Some Democratic strategists worry that these intraparty tensions could be seized upon by Republican opponents. Republicans have broadly supported Israel and have sought to criticize Democrats who oppose U.S. support for Israel. A Republican National Committee spokeswoman, Kiersten Pels, accused Democrats of allowing a dangerous strain of pro-terrorist, anti-American extremism to take root in the party, saying it will turn off swing voters in the midterms.
Frank Lowenstein, a former special envoy for Israeli-Palestinian negotiations under President Barack Obama and now a policy fellow at J Street, a pro-Israel lobby that positions itself as a rival to AIPAC, warned that substantial AIPAC funding may shift toward Republican candidates as a result of the intraparty disputes. He said, quote, “There’s a lot of AIPAC money that will now go to Republican candidates as a result of this.”
At the same time, analysts and campaign operatives cautioned that the overall electoral impact of the anti-AIPAC movement remains uncertain. Hundreds of Democratic candidates are competing in primaries across the country, and the majority of contests have yet to conclude. With many primaries still to occur, it is unclear how many challengers who have made opposition to AIPAC a focal point of their campaigns will prevail in securing nominations.
Conflict Dynamics Underpinning the Debate
At the core of the debate are two major international conflict dynamics that have intensified intra-party disputes: Israel’s military campaign in Gaza and the broader confrontation with Iran. Several of the candidates opposing AIPAC have leveled strong moral and legal criticisms of Israel’s conduct in Gaza and of potential military escalation toward Iran. Those candidates argue that U.S. policy and organizational influence have enabled or supported actions they see as indefensible.
Israeli and U.S. officials dispute those characterizations. Israel denies that its operations amount to genocide and says it seeks to limit civilian harm while distinguishing between civilians and fighters who operate in densely populated areas. The United States and Israel also dispute claims that any war against Iran is illegal, describing goals that include regime change or preventing Tehran from acquiring a nuclear weapon as legitimate national security objectives.
AIPAC’s spokeswoman dismissed the genocide accusations as a legally baseless blood libel. Those sharply divergent narratives remain central to the debates unfolding in Democratic primaries and to how voters and activists evaluate candidates’ positions.
What Is Known and What Remains Uncertain
What is clear from available data is that anti-AIPAC organizations have significantly increased their engagement in Democratic primaries this cycle, endorsing well over 100 candidates and targeting many incumbents who have taken AIPAC support. What is less certain is the ultimate electoral effect: how many of the endorsed challengers will win their primaries, what the flow of AIPAC dollars will look like in the months ahead, and how these primary fights will shape general election dynamics in key competitive districts and Senate races.
As the primaries progress, observers will watch contested nomination battles where AIPAC’s role and the candidates’ positions on Israel and related conflicts are central campaign themes. For now, intraparty divisions over AIPAC and U.S. policy toward Israel remain a defining fault line in several Democratic primaries heading into November.
