It’s 2025, and the Democratic Party looks nothing like it did a decade ago. The Overton window, the range of “acceptable” political ideas, hasn’t just shifted left; it’s been dragged there by a loose network of organizers, activists, and elected officials who trace their roots to the Democratic Socialists of America (DSA). What started as a fringe group in the shadows of the Cold War has become a force reshaping American politics from within. This series, DSA: The Long March, pulls back the curtain on that journey: from ideological foundations to viral moments, electoral wins, and costly falls. We’ll trace the infiltration, the radicalization, and the risks, because if we don’t expose it now, the spillover from campuses to Congress could hit the streets harder than it already has.
The Quiet Infiltration
The DSA isn’t a traditional party; it’s a decentralized movement, flexible enough to embed itself in the Democratic machine without ever fully owning it. Founded in 1982 by Michael Harrington, a disillusioned socialist who saw the Democrats as a vessel for change, the DSA rejected the old-school vanguard model. Instead, it bet on a “long march through the institutions,” borrowing from Italian Marxist Antonio Gramsci: capture culture, education, and politics from the inside. Harrington’s vision was pragmatic, work within the system to push for universal healthcare, labor rights, and economic equality. But as we’ll explore in Thursday’s deep dive on Harrington, that blueprint has evolved into something more aggressive.
By the 2010s, DSA membership exploded from a few thousand to over 100,000, fueled by Bernie Sanders’ presidential runs and the rage of Occupy Wall Street. Sanders wasn’t DSA, but he amplified them, normalizing terms like “democratic socialism” in prime time. Enter the Squad: AOC, Tlaib, Bush, Bowman, DSA-endorsed insurgents who flipped blue seats and turned social media into a megaphone. Their wins weren’t accidents; they were the fruit of Justice Democrats and local chapters canvassing door-to-door, out-organizing incumbents with small-dollar fuel.
This infiltration isn’t conspiracy, it’s strategy. DSA chapters coordinate with socialist-leaning campus groups, where Marxism has gone mainstream. In 2025, surveys show over 40% of Gen Z identifying as socialist-leaning, up from 20% a decade ago. Colleges aren’t just breeding grounds; they’re recruitment hubs, churning out activists who carry the ideology into party primaries. The result? Policies once fringe, like defunding the police, Green New Deal resolutions, and “from the river to the sea” rhetoric, now echo in Democratic platforms, alienating moderates and fracturing coalitions.
The Overton Shift and the Cost
The DSA’s loose structure, no top-down commands, just shared goals, lets it adapt and spread. But it’s also its Achilles’ heel. As we’ll see in modules on AOC and Tlaib, the push left has mainstreamed ideas like abolishing ICE and reparations, but at what price? 2024 primaries showed the backlash: Bush and Bowman ousted by AIPAC-funded challengers, their radical stances alienating even progressive voters. Yet the window stays open, Elizabeth Warren endorsing Bowman signals institutional buy-in, even as the party grapples with internal power struggles.
This isn’t just electoral drama; it’s a warning. Socialism’s college-to-Congress pipeline has made Marxism palatable, repackaged as “equity” and “justice.” But history whispers: unchecked, it spills into unrest. We’ve seen glimpses, campus occupations, street protests echoing 2020. Politically combating this means exposing the mechanics: how DSA’s electoral arm pulls strings without fingerprints, how it radicalizes the base while moderates flee.
Why This Series Matters Now
DSA: The Long March isn’t a hit piece; it’s a roadmap. We’ll break it down module by module: Harrington’s origins (Thursday), Sanders’ spark, AOC’s spectacle, Tlaib’s confrontation, Bush and Bowman’s crash, and Mamdani as the potential phoenix, ending on the cliffhanger: power or failure? Each drops Thursday on Substack, with full video segments on X and YouTube for the visual dive.
In 2025, with the midterms looming and cultural battles raging, understanding this march isn’t optional. It’s how we reclaim the center, before the long road leads somewhere irreversible.
