List of socialist members of the United States Congress
From Wikipedia, the free encyclopedia
The following is a list of members of the United States Congress who have declared themselves to be socialists or have been a member of a socialist organization in the United States.
History
From the 1890s to the 1910s, most socialists who won election to public office ran on the Populist or Socialist Party of America (SPA) ballot lines. While the SPA won a few federal elections, its electoral power was much greater in local and state elections, and briefly held over 1,000 local offices.[1] During the First Red Scare, the House of Representatives twice refused to seat socialist Victor Berger, who would be convicted of violating the Espionage Act of 1917 and again won his seat.[2]
Only a handful of members of Communist Party USA (CPUSA) ever won federal office, and never as open Communists. The Second Red Scare and McCarthy era resulted in persecution of socialists, removal of socialists from unions, and weaker socialist electoral outcomes.[3]
Starting in the 1980s, a small number of social-democratic and socialist Democrats affiliated with the Democratic Socialists of America (DSA). After the Bernie Sanders 2016 presidential campaign and explosion of DSA membership, DSA rapidly gained half a dozen seats in the House. In 2021, there were more socialists in Congress than any point in US history,[4][5] most of whom are members of DSA.[6] After Cori Bush and Jamaal Bowman lost re-election and Greg Casar and Summer Lee lost DSA endorsement, that number shrank again.

Notable progressive but not socialist members
The list below includes members who have sometimes been described as socialist, but are / were not ideological socialists or sincere members of a socialist organization:
- Maxwell Frost (2023–, FL-10) is a progressive and the first Generation Z member of Congress. Frost explicitly does not identify as socialist, saying "my family fled that".[60]
- Shri Thanedar (2021–, MI-13) is a Democrat and expelled DSA member. Thanedar is not considered a socialist or reflective of the values of the organization.[61][62]
- Ilhan Omar (2019–, MN-5) is a member of "The Squad". In 2019, Donald Trump insulted Omar as an "America-hating socialist" while a crowd chanted "send her back".[63][64][65][66] Omar has never identified as socialist nor endorsed socialism. Omar was not endorsed by DSA and is not a DSA member,[67] though DSA called her a "friend of DSA".[68] In 2020, Jacobin described her as "one of the leading lights of the democratic socialist movement".[69] In 2019, an Omar staffer claimed: "[S]he is proud to call herself a democratic socialist".[70]
- Ayanna Pressley (2019–, MA-07) is a member of "The Squad". Pressley explicitly does not identify as socialist.[71][72]
