Mamdani Is Right: the Democratic Party Forgot Who Built It, and Socialists Are Coming to Collect

House Democrats sat down, sharpened their pencils, and produced a manifesto. Against socialism. In the year 2025. While working people across the country cannot afford rent, groceries, or a medical emergency. Their grand strategy for reclaiming relevance is to publish a document repudiating the one political movement actually energizing their base. Zohran Mamdani, the mayor-elect of New York City and a democratic socialist, laughed when he heard about it. “I’m not interested in writing a manifesto or frankly, in reading one,” he said. “I’m interested in delivering.”

That single sentence contains more political intelligence than every page of that manifesto combined.

Mamdani won the mayor’s office running on free bus service, frozen rents, universal childcare, and a higher minimum wage. He defeated a Republican in Curtis Sliwa and the entire Democratic old guard behind Andrew Cuomo at the same time. Fifty thousand volunteers knocked on 1.6 million doors. The NYC-DSA, with its 8,800-plus members, provided the field infrastructure that the party establishment could not buy with all its dark money. And since his June primary win, the DSA says democratic socialism has “soared in popularity here and across the nation.”

Then along comes Donald Trump, slapping the word “communist” on Mamdani like a bumper sticker, because that is the only gear he has. Mamdani shut it down on Meet the Press with two words: “I am not.” He pointed to Dr. King, who in 1961 said, “Call it democracy or call it democratic socialism. There has to be a better distribution of wealth for all of God’s children in this country.” That is the tradition Mamdani is claiming. Not Stalin. Not Mao. Martin Luther King Jr. and the New Deal. The same New Deal that built the American middle class the Democratic Party now takes credit for while actively dismantling its legacy.

Because here is what the manifesto writers do not want to confront. A Gallup poll in September found that roughly two-thirds of Democrats view socialism positively, up from 50 percent in 2010. That is not a fringe. That is the base. Alexandria Ocasio-Cortez, who endorsed Mamdani alongside Bernie Sanders, put it plainly when asked to define democratic socialism: “It’s this radical idea that working people have economic rights.” Housing. A livable wage. Health care. Child care. These are not radical demands. They are floor-level requirements for human dignity in the wealthiest nation on Earth.

The establishment’s response to a movement that turned out 50,000 volunteers and won the largest city in America is to write a paper telling people to stop believing in things. The Cuomo machine spent lavishly. The billionaire class lined up behind the status quo. And a 33-year-old state assemblymember with a socialist platform beat them all. The lesson is not complicated. When you give people something to vote for, they vote. When you offer them nothing but “we are not the other guy,” they stay home, and the other guy wins.

Mamdani said democratic socialists are “going back to what the party used to be.” He is right. The Democratic Party used to build public housing, regulate banks, invest in infrastructure, and tax the rich at rates that would make today’s centrists faint somewhere. Somewhere between then and now, the party traded its spine for a corporate donor list and lost three elections it should have won.

The path forward is not a manifesto. It is a door. Knock on it. Tell people what you will deliver. Then deliver it. That is what won New York City, and it is the only thing that will win what comes next.
