NY primaries sweep

A slate of democratic socialist candidates backed by New York City Mayor Zohran Mamdani swept Democratic House primaries in New York on Tuesday, with Brad Lander ousting Representative Dan Goldman and Darializa Avila Chevalier defeating Representative Adriano Espaillat.

The BBC said Lander defeated Goldman in New York's 10th congressional district, while it also reported that Claire Valdez defeated Brooklyn Borough President Antonio Reynoso in New York's 7th district and that Darializa Avila Chevalier won in New York's 13th district.

NPR described the night as Mamdani’s “political gamble” paying off, saying all three of Mamdani’s endorsed candidates for Congress were victorious and that the biggest upset came in New York's 13th district where Darializa Avila Chevalier narrowly defeated Adriano Espaillat.

In a watch-party moment, Mamdani told the crowd that the results showed his mayoral win “was not the end of a political movement, it was the beginning,” as chants of “D.S.A.! D.S.A.!” rose during his remarks.

The Washington Post framed the sweep as a Democratic Socialists of America-backed expansion of support, saying the DSA “has found its strongest support among Whiter, highly educated neighborhoods” while Tuesday’s wins also drew backing from Black and Latino voters.

Sanders and Jeffries

Sen. Bernie Sanders and the Democratic Socialists of America used the New York results to demand terms from the Democratic Party, with Fox News quoting a DSA leader saying, "Don’t even try it," and adding, "We control these areas."

Sanders declared that “working people” across New York “delivered a powerful message: the era of status quo politics is over,” and he urged Democrats that “if Democrats regain control of Congress next year, they must listen to the people who put them in office.”

The BBC reported that Trump referenced Mamdani’s endorsement successes, writing that America would “never be a communist country!” and that Mamdani rejected the “communist” label Trump repeatedly used during his mayoral run.

In the same BBC account, Hakeem Jeffries was quoted saying, “We have agreed to strongly disagree,” as the article described the primaries as exposing divisions over the Israel-Gaza war.

The Washington Post also described backlash within the Democratic Party, quoting Jaime Harrison warning against “fighting a two-front war, one against the Republicans and the other friendly fire in the back.”

Midterms and next tests

The BBC said the primaries were seen as a test of Mamdani’s influence as he helped boost the profiles of progressive political candidates, while it also noted that establishment Democrats in Washington warned left-wing candidates might not appeal to swing voters in the November midterms.

MS NOW said “The harder tests come next,” pointing to Colorado where Melat Kiros, backed by both the DSA and Sanders, is attempting to unseat Rep. Diana DeGette, and it described additional tests in August in Missouri, Michigan, and Wisconsin.

The Washington Post added that upcoming congressional primaries in Denver, Detroit and South Florida would test the group’s power in places where it has less of a track record of success and no Mamdani equivalent to boost candidates.

NPR said the districts heavily favor Democrats, meaning Valdez, Lander and Avila Chevalier are expected to win their general election matchups in the fall, but it still framed the night as a first major test for Mamdani’s political movement.

VTDigger reported that the three Mamdani-and-Sanders-backed candidates—Brad Lander, Claire Valdez and Darializa Avila Chevalier—were expected to easily win office in this fall’s general election, while it also quoted Sanders calling for momentum with “Let’s organize and continue winning elections.”
