Zohran Mamdani was sworn in as New York City's mayor by Bernie Sanders on New Year's Day.
What put him there was not just a campaign – it was an eight-year socialist infiltration plan written down and published.
The plan names exactly which industries socialists should target – and the results are already showing up across America.
How the DSA Teachers Union Infiltration Plan Quietly Spread Across America
In 2018, the Democratic Socialists of America released a pamphlet titled "Why Socialists Should Become Teachers," directing members to take jobs in education not to teach children but to radicalize unions from the inside out.
The strategy is not new. Vladimir Lenin declared that trade unions are "a school of communism" – a training ground for building revolutionary political power through organized labor. The DSA simply updated the curriculum.
The document declares teaching "a strategic industry to organize" and instructs DSA members to build "a militant minority of class-conscious teachers" capable of steering their unions toward socialist political goals that have nothing to do with schools.
The West Virginia teachers' strike was their test run.
In February 2018, DSA-aligned teachers defied state law and walked off the job in a wildcat strike. Socialist organizers embedded inside the union did not just fight for higher wages – they pushed union leaders to demand that the money come from higher taxes on corporations and fossil fuel companies.
A standard labor dispute became a vehicle for socialist tax policy. The union won. The socialists took notes.
Tyler O'Neil at the Daily Signal documented how the DSA's rank-and-file strategy, adopted by the Young Democratic Socialists of America as a national priority, explicitly coaches young radicals to seek employment in "strategic industries" including education, logistics, and healthcare.
The DSA spelled it out in their own documents: "Reconnect the labor movement to the socialist movement in order to strengthen the militancy and class consciousness of the multiracial, multigendered working class to fight capitalism."
Every school board member, state legislator, and grandparent in America should read it.
America's largest unions were already doing the Democrat Party's bidding long before the DSA arrived.
In a single election cycle, the SEIU spent $13.4 million backing Democrats, AFSCME spent $15.5 million opposing Republicans, and the National Education Association gave $2.44 million to Democrats while sending less than $65,000 to Republicans – then funneled millions more to leftist nonprofits pushing causes most of their members have never heard of and would never vote for.
Now the DSA is moving inside those organizations.
DSA members have since been elected to lead major teachers unions in Los Angeles and Boston.
In New York City, a DSA-linked reform caucus identified the United Federation of Teachers – the largest local teachers union in the country – as the prime entry point for socialist organizers.
When Mamdani ran for mayor, DC 37 – New York City's largest public-sector union with 150,000 city workers and a history of backing establishment Democrats – endorsed him.
Socialists called that endorsement a direct victory for rank-and-file organizing.
They were not wrong.
How Zohran Mamdani Proved the DSA Rank and File Strategy Works
Conservatives focused on Mamdani as a candidate missed the larger story.
His election was the proof that the strategy works.
The DSA's own statement after his victory said the campaign was "powered by over 100,000 volunteers," with DSA members organizing "in our unions and communities" across New York City.
Mamdani himself told a national podcast, "My party is the Democratic Party, and my organization is DSA."
The union that used to fight for workers' pensions is now fighting for the people who want to abolish the Senate.
The socialists who spent eight years placing members in government schools, hospitals, and logistics hubs didn’t do it so those workers could get a raise.
They did it to build what O'Neil describes as a permanent organizing infrastructure with "stable funding streams, paid staff, political influence, and the ability to mobilize large numbers of people" – all pointed at reshaping the Democrat Party from the inside out.
Mamdani's DSA co-chair Megan Romer confirmed the organization's actual agenda just weeks after his inauguration: abolish the Senate, abolish ICE, abolish prisons, and tear apart American democracy as it exists today.
Mamdani does not say those words from City Hall.
But the people who put him there do.
And they have a written plan – published, public, and already working – to put more of him everywhere.
