I want to show you a magic trick, because I used to do it for a living. You take a politician who promised cheaper child care, a freeze on rent, and city-run grocery stores, and you make all of that disappear. In its place you produce a single word — “Marxist” — and the audience, who came in worried about their rent, leaves the theater worried about the Bolsheviks instead. James Freeman’s “Here Come the Mamdani Marxists!” in Wednesday’s Journal is that trick, performed competently, and I can name every move because we who built these operations practiced them on tighter deadlines than his.

Start with the headline, because the headline is the whole operation in miniature. “Here Come the Mamdani Marxists!” — exclamation point and all — is what operators call the manufactured-panic frame. It does not invite you to weigh a child-care subsidy against its cost. It tells you the Reds are coming over the hill. The exclamation point is not punctuation; it is stage direction. Whenever you see one of those riding atop an op-ed about municipal budgeting, an operator somewhere is doing the thing I was paid to do, which is to move the reader from the language of arithmetic into the language of siege.

The engine underneath is guilt-by-doctrine, and it is older than any of us. The move is to find the most alarming label available — here, “Marxist-Leninist,” a phrase doing a great deal of unpaid labor — and then attach it to a man, and then treat the label as having settled the argument. He took the oath on a Quran. He calls himself a democratic socialist. He said he would govern “expansively and audaciously.” Freeman lines these up not as facts to be examined but as exhibits in a doctrinal indictment, so that by the time you reach the rent freeze you are no longer asking whether a rent freeze is a good idea. You are asking whether you are about to live under one of the regimes that the word “Leninist” was built to summon. That substitution — the policy swapped out for the doctrine — is the trick, and it is the only trick the piece has.

Watch what gets disappeared in the swap. A rent freeze is a concrete municipal policy with concrete winners and losers, and the people it costs are not “free people who built things.” They are landlords, and the larger the portfolio the larger the cost. Free child care has a price and a beneficiary, and the beneficiary is a parent who currently pays more for day care than for rent. City grocery stores are an old, unglamorous idea about food deserts. You can argue every one of these on the merits — operators love when you argue them on the merits, because we have already won by then, having gotten you to fight on the doctrinal field instead of the distributional one. The question Freeman needs you not to ask is the simplest one: who benefits when the rent freeze never happens? Name them, and the “Marxist!” panic looks less like a warning and more like a service rendered to the people who own the buildings.

Then there is the tell, the part where the operation stops pretending it is an argument. Freeman points approvingly at Representative Chip Roy’s “MAMDANI Act,” a bill to bar immigrants who hold Marxist or, the bill helpfully adds, Islamist doctrines. A man’s name turned into an acronym turned into a statute is not policy debate. It is delegitimization with a gavel. The goal of a bill like that is not to pass; it is to fuse the words “Marxist” and “Islamist” and the mayor’s name into one object you are meant to reject without inspection. When the operation reaches for the man’s religion and his immigrant story in the same breath as his doctrine, that is no longer a disagreement about tax policy. That is the civilizational frame, and the civilizational frame has only ever had one purpose, which is to place a person outside the circle of people whose ideas you have to take seriously.

I will concede Freeman the strongest version of his case, because the only honest way to disarm this is to refuse to do back to him what he did to Mamdani. A self-described socialist running the country’s largest city is a real story, and a skeptic of his program is entitled to a hearing. But Freeman did not write the skeptic’s column. He wrote the panic, and a panic is not a critique — it is a way of making sure the critique never has to be made. The pied-à-terre video, the parade he skipped, the children’s bedtime rule — these get folded in not because they bear on whether child care should be subsidized, but because once the siege frame is up, every detail becomes another Red over the hill.

So here is the appropriate response to a man who has dressed a landlords’ brief in the costume of anti-communism. Take off the costume and hold it up to the light. What is left when you subtract the exclamation point and the doctrine and the acronym is a mayor who said he would lower the cost of living in an unaffordable city, and a columnist who would very much prefer you fear that than examine who profits from your fear. I ran versions of this trick for years. The reveal is always the same: there was never a Bolshevik. There was only your rent, and the question of who gets to keep raising it.
