The New York 10th District primary results delivered a striking upset, with former city comptroller Brad Lander unseating incumbent Representative Daniel Goldman in a contest that spotlighted the shifting politics surrounding Israel. Running to Goldman’s left, Lander entered the race as something of a challenger but emerged with a commanding win.

A Race Defined by Israel and Ideology

The matchup carried significance well beyond the district’s borders. Goldman, the sitting congressman representing parts of Manhattan and Brooklyn, found himself defending his seat against a progressive opponent at a moment when Democratic attitudes toward U.S. policy on Israel have been visibly evolving.

Lander, positioning himself firmly to the left, tapped into that shift and built a coalition broad enough to overcome the advantages typically enjoyed by an incumbent.

How the Boroughs Voted

The results broke down clearly across the two boroughs that make up the district, and Lander dominated both.

• Brooklyn: Lander posted a commanding lead of 45 points, pulling in 51,075 votes with 93 percent of the count in.
• Manhattan: Lander carried the borough as well, though by a narrower margin of 11 points, gathering 32,586 votes with 86 percent reporting.

The Brooklyn blowout, in particular, powered much of his overall victory.

Where Lander’s Strength Came From

A closer look at the precinct-level data reveals the contours of Lander’s winning coalition. His support was especially concentrated among certain groups and neighborhoods:

• Younger residents: Lander led by 21.4 points, taking 61 percent to Goldman’s 39 percent.
• Majority college-educated areas: One of his strongest showings, Lander won by 38.6 points, 69 percent to 31 percent.
• Higher-income areas: Lander dominated here with a 40.1-point margin, claiming 70 percent of the vote.
• Majority Hispanic areas: He carried these by 34.3 points, winning 67 percent to 33 percent.

Where Goldman Held On

Goldman was not shut out everywhere. The incumbent found his footing in lower-income areas, where he reversed the trend and led Lander by 13.8 points, taking 57 percent to Lander’s 43 percent.

That pocket of strength, however, proved far too narrow to offset Lander’s overwhelming advantages across younger, wealthier, and more highly educated parts of the district.

The Bigger Picture

Lander’s victory adds to a broader story unfolding across New York City’s Democratic primaries, where progressive and left-leaning challengers have been making significant gains. His win over Goldman, an established incumbent, underscores how quickly the political ground can shift, particularly on issues like Israel that have increasingly divided the Democratic coalition.

With the district leaning solidly Democratic, Lander now stands as the heavy favorite to claim the seat in the general election this fall.
