New York City Mayor Zohran Mamdani saw a clean sweep Tuesday, with House candidates backed by the democratic socialist mayor winning three congressional primaries — ousting two incumbent Democrats in the process.

Mamdani’s show of force were the latest preview of the ideological battles to come, as Democrats vying to win control on Capitol Hill in November’s midterm elections also look ahead to the 2028 presidential race.

In the 13th District, democratic socialist Darializa Avila Chevalier defeated Rep. Adriano Espaillat, the chairman of the Congressional Hispanic Caucus, in a race that – like the other New York contests – focused largely on the United States’ relationship with Israel.

Another democratic socialist, Assemblywoman Claire Valdez, defeated Brooklyn Borough President Antonio Reynoso in the race to replace outgoing Rep. Nydia Velázquez in the 7th District.

And in the 10th District, Mamdani ally and former city comptroller Brad Lander defeated Rep. Dan Goldman.
