Despite Winning New Jersey Special Election, Anti-Israel Candidate Underperforms in Heavily Jewish Town

In Thursday night’s US congressional election in the 11th district of New Jersey, Jewish voters seemed to defect from the Democratic nominee in massive numbers, potentially foreshadowing a significant shift in Jewish voting patterns.

Analilia Mejia, a progressive activist known for her sharp condemnations of Israel, comfortably won the special congressional election in New Jersey in the deep-blue district by a margin of 60 percent to 40 percent.

Despite defeating her Republican opponent by 20 points, however, pundits pointed out that Mejia underperformed expectations and that Democrats hemorrhaged support among heavily Jewish communities. 

In Livingston, New Jersey, a town with a significant Jewish population, Mejia barely eked out a 51-49 majority over Joe Hathaway, a staggering sea-change from recent elections. The deep-blue town voted for Democratic Gov. Mikie Sherrill and Democratic presidential nominee Kamala Harris by margins of 0.5 and 12 points, respectively. Taking into account party registration, the town has seen a shift to the political right by over 50 percent since 2024.

Though Mejia won Thursday’s race by a comfortable margin, experts pointed out that the progressive insurgent underperformed throughout the affluent suburban district. When taking into account party registration patterns, Mejia underperformed in Millburn by 23 points, North Caldwell by 10 points, South Orange by 7 points, and West Caldwell by 6 points, among others.

Spectators suggested that Mejia’s impressive margin of victory could be attributed to anti-Trump sentiment and massive turnout among Democrats and depressed turnout from Republicans.

Mejia’s positions on Israel, once considered fringe within the party, are increasingly becoming more mainstream, particularly in elections dominated by liberal voters. Her rhetoric on Israel, which critics say is one-sided and inflammatory, has drawn backlash from moderates and pro-Israel Democrats.

The outcome raises fresh questions about the party’s direction heading into national elections. While progressives see momentum, others worry candidates like Mejia could alienate Jewish and moderate voters while complicating efforts to maintain a broad electoral coalition. Her victory is likely to deepen internal party tensions, especially as debates over Israel grow more polarized and politically charged.

Mejia has said Israel’s actions in Gaza amount to “genocide,” a position that put her well to the left of many mainstream Democrats. She has aligned herself with calls for stronger conditions, or outright opposition, to US military support for Israel, reflecting the broader progressive wing’s push to reassess the traditional US-Israel relationship. She has also aimed sharp criticism toward the American Israel Public Affairs Committee (AIPAC), the preeminent pro-Israel lobbying group in the US, calling the organization “horrendous” and accusing it of dividing the Democratic Party. 

A progressive organizer with a record of criticizing Israeli government actions, Mejia benefited from a coalition of younger voters, activists, and highly engaged ideological blocs. Her win is consistent with recent polling trends showing a generational divide within the party, with younger Democrats expressing more skepticism toward Israel than older cohorts.

Mejia’s struggles in heavily Jewish and moderate areas of the district could forecast a split between the Democratic Party and what has been historically one of its most reliable voting blocs.

Since Hamas’s Oct. 7, 2023, massacre across southern Israel launched the Gaza war, the Democratic Paty’s rhetoric toward Israel has become increasingly hostile. Progressive Democrats, such as Reps. Ilhan Omar (MN) and Alexandria Ocasio-Cortez (NY), have accused Israel of committing “genocide” in Gaza.

This past week, approximately 80 percent of Democratic senators voted to halt military aid transfers to Israel, citing poor humanitarian conditions in Gaza and dismay over the US-Israeli war with Iran.
