# Democratic Socialists of America The **Democratic Socialists of America** (DSA) is the largest socialist organization in the United States — claiming over 120,000 members as of 2026 — and the vault tracks it for two reasons that have nothing to do with endorsing or opposing its politics. First, DSA is the organizational vehicle through which "socialism" re-entered mainstream American political discourse after 2016, which makes it essential context for understanding the right-wing attack frame that labels the entire [[Democratic Party]] as socialist or communist. Second, the DSA's electoral strategy — running members in Democratic primaries rather than as third-party candidates — represents a distinct theory of political change that the vault documents alongside the right's own primary-challenge strategies. ## The origin: Michael Harrington's merger DSA was founded in 1982 from the merger of two organizations: Michael Harrington's Democratic Socialist Organizing Committee (DSOC, founded 1973) and the New American Movement (NAM, a post-New Left organization founded 1971). Harrington — the author of *The Other America* (1962), the book that helped catalyze Lyndon Johnson's War on Poverty — was the preeminent American democratic socialist of the postwar era. His strategic conviction was that socialists should work *within* the Democratic Party rather than building a third party, on the theory that the American two-party system made third parties structurally unviable and that the Democratic Party's coalition could be moved leftward from within. This "realignment" strategy — the decision to contest Democratic primaries rather than run as Socialists — defines DSA's electoral approach to this day and distinguishes it from virtually every other socialist organization in American history. DSA is not a political party. It does not appear on ballots. Its members run as Democrats, win Democratic primaries, and serve as Democrats — but they maintain a separate organizational identity, pay DSA dues, and are accountable to DSA's internal democratic processes (national conventions, chapter votes, working groups). ## The 2016 surge and the Sanders effect DSA was a marginal organization for most of its existence — membership hovered between 5,000 and 10,000 from the 1990s through 2015. The transformation began with [[Bernie Sanders]]'s 2016 presidential primary campaign, which demonstrated that a candidate running explicitly as a "democratic socialist" could win 43 percent of the Democratic primary vote and carry 23 states. Sanders was not a DSA member, but his campaign normalized the label and created a generation of activists who sought an organizational home to the left of the Democratic establishment. DSA membership surged from roughly 6,000 in early 2016 to over 30,000 by mid-2017. The second surge came after [[Alexandria Ocasio-Cortez]]'s June 2018 primary upset of ten-term incumbent Joe Crowley in New York's 14th Congressional District — the most dramatic DSA electoral victory and the proof-of-concept for the primary-challenge strategy. Membership peaked at approximately 95,000 in 2021 before declining and then rebounding to over 120,000 by mid-2026. ## The electoral record DSA's electoral strategy has produced a distinctive track record. As of 2026, DSA members or endorsed candidates hold over 250 elected offices across all levels of government, with roughly 90 percent elected since 2019. At the federal level, DSA's highest-profile members have included [[Alexandria Ocasio-Cortez]] and Rashida Tlaib in the House of Representatives. Cori Bush (Missouri) and Jamaal Bowman (New York), both DSA-endorsed members of Congress, lost their Democratic primaries in 2024 — Bush to Wesley Bell in August 2024 and Bowman to George Latimer in June 2024 — in races where pro-Israel PAC spending (particularly AIPAC's United Democracy Project) was a major factor. The primary losses demonstrated both the vulnerability of DSA-aligned incumbents to well-funded primary challengers and the specific role of the Israel-Palestine issue as a fault line within the Democratic coalition. The municipal precedent came in Buffalo in 2021, when DSA member [[India Walton]] defeated four-term Mayor [[Byron Brown]] in the Democratic primary, only for Brown to win the general election as a write-in with police-union and Republican backing. At the state and local level, DSA's most significant 2025 victory was [[Zohran Mamdani]]'s upset win in the New York City mayoral race — a DSA assemblyman defeating the Democratic establishment in a city of 8 million. The Mamdani victory, combined with DSA-backed candidates winning June 2026 Democratic primaries in New York and Washington, D.C., prompted [[Donald Trump]] to brand Democrats "godless communists" and "animals" at the Faith and Freedom Coalition — deploying the [[Red Scare]] frame that the vault tracks as a recurring right-wing rhetorical strategy. ## The ideology: democratic socialism, not [[Communism]] The deliberate conflation of democratic socialism with [[Communism]] is one of the right's most effective rhetorical weapons — and one of the reasons the vault documents the distinction carefully. Democratic socialism advocates for a stronger social safety net, higher taxes on concentrated wealth, universal public services (healthcare, education, housing), and stronger labor protections *within the existing democratic and broadly capitalist system*. It does not advocate for state ownership of all means of production, one-party rule, or the abolition of markets. The Nordic social democracies (Denmark, Sweden, Norway) are the closest real-world analogs to DSA's policy platform — mixed economies with strong welfare states, robust unions, and democratic governance. The conflation works politically because "socialist" carries Cold War connotations in American discourse that "social democrat" does not — and because DSA's own internal diversity includes tendencies (Marxist, ecosocialist, libertarian socialist) that genuinely do advocate for more radical transformation than the organization's mainstream electoral platform reflects. The gap between DSA's internal ideological range and its electoral platform is a productive tension the organization has never fully resolved. ## The right's use of DSA For the vault's purposes, DSA matters less as a political organization than as a *label* — the word "socialist" that the right deploys as an attack against the entire Democratic Party. When Republican campaign ads call a moderate Democrat a "socialist," the underlying logic is guilt by association with DSA and its most visible members. The strategy assumes — often correctly — that "socialist" remains a negative valence term for persuadable voters, even as polling shows increasing acceptance of the label among younger Americans. The [[Red Scare]] entry tracks the longer history of this rhetorical strategy. DSA's post-2016 visibility gave the strategy new material: specific candidates (Ocasio-Cortez, Mamdani), specific policy proposals (Medicare for All, the Green New Deal), and a specific organizational identity that could be pointed to as evidence that "the socialists" were not a historical memory but a present political force. Whether this framing helps or hurts the right is one of the live questions of the 2026 midterm cycle. ## See also [[Alexandria Ocasio-Cortez]] · [[Bernie Sanders]] · [[Zohran Mamdani]] · [[India Walton]] · [[Working Families Party]] · [[Donald Trump]] · [[Red Scare]] · [[Communism]] · [[Democratic Party]] · [[Populism]]
