Brad Lander Wins Democratic Primary Against Goldman

Brad Lander won the Democratic primary over incumbent Rep. Dan Goldman in New York’s 10th Congressional District. Center outlets place the result in a broader account of Mamdani’s influence and progressive gains, while also noting disputes over Israel and immigration. Right-leaning outlets frame it as part of a socialist or leftward shift in Democratic politics, emphasizing party divisions and, in some coverage, Goldman’s anti-Trump profile.
