A major shift is unfolding in American electoral politics as traditional, unconditional support for Israel faces unprecedented challenges from both Democratic and Republican factions. This realignment was recently highlighted in Michigan's Democratic Senate primary, where Abdul El-Sayed secured a decisive victory over sitting Representative Haley Stevens. El-Sayed campaigned openly on labeling Israel's military campaign in Gaza a genocide, breaking sharply with Stevens and the party's traditional donor class. The victory came despite nearly $65 million in advertising, largely funneled through the American Israel Public Affairs Committee (AIPAC) on behalf of Stevens, and an endorsement from the state's governor.
This electoral outcome mirrors a growing, albeit uneven, trend inside the halls of the United States Congress. In July, 103 House Democrats voted in favor of an amendment introduced by Kentucky Republican Representative Thomas Massie to block $3.3 billion in military assistance to Israel. Just two years prior, a similar measure garnered only 37 Democratic votes. A parallel shift occurred in the Senate in April, where 40 out of 47 Senate Democrats voted to halt a $450 million weapons package over concerns regarding Israel's operations in Gaza and Iran. That figure stood at 27 the previous July and just 15 the year before. While these legislative challenges ultimately failed, the margins of defeat have grown increasingly narrow.
The shifting political landscape in Washington is deeply tied to the humanitarian toll in Gaza. Since October 2023, military operations have killed more than 73,000 Palestinians and wounded over 174,000, according to the local Health Ministry. Global broadcasting of widespread destruction, mass displacement, and forced starvation across the enclave has prompted an increasing number of US lawmakers to openly challenge Israeli policies, leaving party leaders on both sides struggling to manage the dissent within their ranks.
According to Alon Liel, the former director general of the Israeli foreign ministry, support is also fracturing among American Jews. Liel attributes this shift to a general American fatigue with the broader Arab-Israeli conflict, alongside the reality that Israel is no longer perceived as the underdog. This erosion of support has been further accelerated by the high casualty rates in Gaza and ongoing illegal settler violence in the occupied West Bank. Liel noted that growing diplomatic criticism from European nations is reinforcing the transformation of American attitudes, adding that AIPAC's influence is in decline as organizations like J Street act as a counterbalance.
Public opinion data indicates that congressional skepticism is trailing behind a shift that has already occurred among voters. An Economist/YouGov poll from August revealed that 45 percent of American voters believe Israel is committing genocide against Palestinians, compared to 31 percent who disagree—a margin that remains consistent across Democrats, independents, and self-described political moderates. Similarly, Gallup tracking shows that overall approval of Israel's military campaign in Gaza has dropped from 50 percent to 32 percent since the conflict began, while disapproval has climbed from 45 percent to 60 percent.
The most pronounced shift has occurred within the Democratic base. Democratic approval of Israel's conduct in Gaza has plummeted to just 8 percent, while support for continuing military aid fell from 55 percent to 43 percent within a single year. Historically, this represents a complete reversal of long-term trends. In 2001, more than half of Democratic voters expressed sympathy for Israel, while only 16 percent sided with Palestinians. Today, those numbers have inverted, with 59 percent of Democrats sympathizing with Palestinians compared to 21 percent for Israel.
While the Republican coalition has shifted less dramatically, younger conservatives are showing measurable change. Unfavorable views of Israel among Republicans under the age of 50 rose from 35 percent to 50 percent over a three-year period, a trend largely attributed to fatigue with US military interventions in the Middle East.
AIPAC's long-standing ability to enforce bipartisan consensus by making criticism of Israel an electoral liability is showing signs of wear. Although the group successfully funded the defeat of Representative Cori Bush in Missouri two years ago, its record spending in Michigan failed to save Stevens. Elsewhere this cycle, Representative Adriano Espaillat lost his primary to a democratic socialist candidate who ran on an explicitly anti-military aid platform.
Simultaneously, a different kind of skepticism is taking root on the political right. Prominent conservative media figures, including Tucker Carlson, Marjorie Taylor Greene, and Megyn Kelly, have introduced "America First" skepticism regarding foreign aid to Israel into mainstream MAGA discourse. While this has not yet cost a Republican incumbent their seat, it has legitimized a non-interventionist stance on Israel within conservative circles for the first time in a decade.
Reflecting on these developments, Yossi Shain, an Israeli international relations scholar and former member of the Knesset, observed that Israel has increasingly become a "toxic brand" in Washington. Former CIA officer John Kiriakou went further, stating that Israel has lost the support of both the American public and the US military, warning that the United States will not indefinitely finance or fight Israel's wars. Observers increasingly agree that the shift is structural, as both Democrats and Republicans arrive at critical conclusions about Israel's actions from entirely different ideological viewpoints.
