The traditional bipartisan consensus supporting Israel in Washington is facing a significant, structural decline as both Democratic and Republican voters express growing fatigue with the conflict. Recent electoral outcomes, such as the defeat of Rep. Haley Stevens in Michigan’s Democratic Senate primary, underscore this shift. Despite nearly $65 million in advertising—much of it funneled through AIPAC—the pro-Israel establishment failed to prevent the victory of Abdul El-Sayed, who campaigned explicitly against the war in Gaza.
Legislative trends in Congress reflect this changing sentiment. In July, 103 House Democrats supported an amendment by Republican Thomas Massie to cut $3.3 billion in military aid to Israel, a sharp increase from the 37 Democrats who backed a similar measure two years prior. Similarly, in April, 40 out of 47 Senate Democrats voted to block a $450 million arms package, citing concerns over Israel’s conduct in Gaza and Iran. While these measures did not pass, the margins of defeat have consistently narrowed.
The humanitarian toll of the conflict has been a primary driver of this shift. According to the Gaza Health Ministry, more than 73,000 Palestinians have been killed and over 174,000 wounded since October 2023. The widespread destruction, mass displacement, and reports of starvation have been documented globally in real time, fueling public outcry.
Public opinion polling highlights the scale of this transformation. An August Economist/YouGov survey indicated that 45 percent of American voters believe Israel is committing genocide, compared to 31 percent who disagree. Gallup data shows approval of Israel’s actions in Gaza has plummeted from 50 percent to 32 percent, while disapproval has risen to 60 percent. Among Democrats, support for military aid has dropped from 55 percent to 43 percent in just one year.
The historical reversal is stark. In 2001, over half of Democratic voters sympathized with Israel, with only 16 percent siding with Palestinians. Today, those figures have essentially inverted, with 59 percent of Democrats now favoring the Palestinian cause. Alon Liel, former director general of the Israeli foreign ministry, attributes this to American fatigue with the Israeli-Arab conflict and the perception that Israel is no longer the underdog.
Liel notes that the erosion of support among American Jews has provided legitimacy to this broader political shift. He further suggests that AIPAC’s influence is waning as it faces competition from groups like J Street and increasing international criticism from Europe. According to Liel, this trend will likely persist until there is a fundamental change in Israeli policy and behavior.
Within the Republican Party, the movement is more subtle but still measurable. While younger Republicans are increasingly critical—with unfavorable views of Israel rising from 35 percent to 50 percent over three years—the shift is also driven by “America First” skepticism. Figures such as Tucker Carlson, Marjorie Taylor Greene, and Megyn Kelly have introduced a new, critical discourse within MAGA media that challenges the necessity of indefinite US intervention in the Middle East.
Yossi Shain, an Israeli international relations scholar and former Knesset member, has characterized Israel as a “toxic brand” in Washington. This sentiment is echoed by former CIA officer John Kiriakou, who argues that Israel has lost the support of the American public and military, warning that the United States will not indefinitely fight foreign wars under pressure.
The political landscape is clearly evolving as both parties approach the issue from different ideological starting points. As the institutions that once maintained bipartisan support struggle to hold the consensus together, the political cost of opposing Israel is visibly decreasing, marking a potential turning point in the US-Israel relationship. The report also notes that if more unevenly, congress has been arriving at a version of the same verdict for months. The report also notes that in April, 40 of the 47 Senate Democrats voted to block a $450 million arms package over Israel’s conduct in Gaza and Iran, up from 27 the previous July and 15 the year before that. The report also notes that with entire neighbourhoods reduced to rubble, mass displacement and forced starvation conditions documented across the enclave, the scale of the destruction has been visible around the world in real time. The report also notes that “It has worsened as a result of the casualties and damage inflicted on Gaza and illegal settler violence in the occupied West Bank.”. The report also notes that against 31 percent who disagree, and this margin holds across Democrats, independents, and self-described moderates alike, an Economist/YouGov poll conducted in August found that 45 percent of American voters believe Israel is committing genocide against Palestinians. The report also notes that whose support for continued military aid dropped from 55 percent to 43 percent in a single year, while their approval of Israeli conduct in Gaza has fallen to just 8 percent, the steepest collapse has come among Democrats. The report also notes that in 2001, more than half of Democratic voters said their sympathies lay with Israel, against 16 percent who sided with the Palestinians; those figures have essentially inverted, with 59 percent of Democrats now siding with Palestinians against 21 percent for Israel. The report also notes that for three decades, AIPAC’s influence rested as much on political pressure as persuasion, helping make unconditional support for Israel a bipartisan norm by making any departure from it a genuine electoral risk.
