The most prominent upset occurred in New York's 13th Congressional District where Mamdani-backed candidate Darializa Avila Chevalier defeated five-term incumbent Democrat Adriano Espaillat, who chairs the Congressional Hispanic Caucus. According to Fox News, Chevalier, a 32-year-old community organizer and democratic socialist, narrowly topped Espaillat. The pro-Israel lobbying group AIPAC funneled an estimated $50 million into the opponents' campaigns of Valdez, Avila Chevalier, and Lander.
In New York's 10th Congressional District, former City Comptroller Brad Lander defeated two-term incumbent Rep. Dan Goldman. This race highlighted the growing divide within the Democratic Party over Israel's war in Gaza, with Lander criticizing Goldman for not being critical enough of Israel's actions. According to CBS News and HuffPost, Lander received heavyweight endorsements from Mayor Zohran Mamdani and Vermont Sen. Bernie Sanders.
The third victory came in New York's 7th Congressional District where Assemblywoman Claire Valdez defeated Antonio Reynoso to replace retiring Rep. Nydia Velázquez. According to Fox News, this race became a proxy fight between the established progressive wing of the Democratic Party and the democratic socialists backed by Mamdani.
These victories come as Democrats hope to flip the House in November's midterm elections. However, Republican strategists are already planning to use Mamdani's influence as a campaign issue, portraying him as too radical for mainstream America. National Republican Congressional Committee spokesperson Mike Marinella told Fox News that 'Zohran Mamdani's socialist brand is as toxic as it comes' and that Republicans plan to use him as a 'bogeyman' against Democrats.
The primaries also saw other notable races including in Utah where former Rep. Ben McAdams won the Democratic nomination in a newly redrawn district centered on Salt Lake City. In South Carolina, state Attorney General Alan Wilson won the Republican gubernatorial nomination in a runoff against Lt. Gov. Pamela Evette.
As Democrats look ahead to November's elections, these primary results suggest a party grappling with its identity in the Trump era. While establishment figures like Jeffries and Hochul face challenges from their left flank, the ultimate test will be whether this progressive energy can translate into victories in competitive districts across the country.
