Candidates affiliated with Democratic Socialists of America, an organization well to the left of the Democratic Party, have scored wins in several of the party’s competitive primaries. It’s very likely that they will win House seats in the November 2026 elections since the candidates reside in progressive strongholds.
Although those candidates have drawn much attention, this is hardly a new trend. Bernie Sanders, the nation’s most prominent identified democratic socialist, has represented Vermont in the House or the Senate since 1990. U.S. Rep. Alexandria Ocasio-Cortez of New York, the movement’s rising star in Congress, has served in the House since 2019. New York Mayor Zohran Mamdani successfully campaigned as a DSA member in 2025.
