The Democratic Party Risks Being Consumed

History rarely repeats itself exactly. More often, it rhymes.

Many commentators searching for historical parallels to today’s Democratic Party instinctively reach for the French Revolution. They imagine the Jacobins overthrowing the Girondins, moderates swept aside by ideological zeal, and political purity replacing practical governance. While the comparison has some merit, a more compelling historical warning lies elsewhere—not in Paris, but in Petrograd. The real cautionary tale is the Russian Revolution of 1917.

The Fatal Mistake of the Moderates

The tragedy of Russia was not simply that the Bolsheviks were ruthless. It was that the moderates consistently underestimated them. The Mensheviks believed they could coexist with the radical left. Alexander Kerensky’s Provisional Government assumed Lenin represented only one voice among many in a broad socialist coalition. They imagined institutions, democratic norms, and political compromise would restrain the revolution’s most extreme faction.

Instead, every concession strengthened Lenin’s position.

Moderates defended radicals against their conservative opponents. They tolerated increasingly revolutionary rhetoric. They insisted unity was more important than confronting extremism within their own ranks. By the time they realized the danger, the Bolsheviks had already captured the party machinery, dominated the streets, and seized the state itself. The result was not simply a change in government. It was the destruction of political pluralism, decades of dictatorship, state terror, economic catastrophe, and the deaths of millions.

The Mechanism, Not the Men

The value of a historical analogy lies entirely in its mechanism, not its melodrama.

I am not suggesting that any faction of the contemporary Democratic Party resembles the Bolsheviks in aim, method, or moral character. Nobody in American politics is storming a Winter Palace. What 1917 illuminates is not a personality but a dynamic, a recurring failure mode of coalitions that contain a disciplined, ideologically confident minority and a larger, less coordinated moderate majority.

The mechanism runs like this. A broad coalition forms around shared opposition to a common adversary. Within it sits a vanguard: smaller in number but greater in conviction, energy, and willingness to enforce conformity. The moderate majority, reasonably enough, prizes coalition unity. It worries far more about the external opponent than the internal one. So it makes a series of individually sensible accommodations—defending the vanguard from outside attack, declining to police rhetoric it privately finds excessive, and treating any internal criticism as a gift to the enemy.

Each accommodation is rational in isolation. Their cumulative effect is to transfer the coalition’s moral center of gravity toward its most committed wing. The vanguard does not need to win a majority. It needs only to make its positions the ones nobody is permitted to question. This is the genuinely useful lesson of Petrograd, and it requires no Leninism to operate. It is a structural truth about how motivated minorities capture institutions when majorities mistake conflict-avoidance for strategy.

Where the Pattern Appears Today

Strip away the historical sentiment, and the contemporary resonances are not hard to find, not in violence or insurrection, but in the quieter grammar of intra-coalition power.

Consider the asymmetry of enforcement. Within the Democratic coalition, deviation toward the center is frequently treated as betrayal, while deviation toward the activist edge is treated as conscience. A moderate who breaks with the base on a contested issue invites a primary challenge; an activist who stakes out a maximalist position invites, at worst, a gentle plea for message discipline. That asymmetry is precisely the Menshevik error: the belief that the threat to the project always comes from the right and never from within.

Consider, too, the politics of language. The party has at times allowed a small number of highly engaged staffers, advocacy organizations, and online constituencies to define which words and positions are acceptable—on crime, immigration, education, and identity often well in advance of, and sometimes against, the preferences of the voters the party needs. When elected officials adopt slogans they did not author and cannot defend and then quietly abandon them after electoral damage, we are watching the vanguard set terms the majority feels unable to refuse in the moment.

And consider the reflex toward unity above correction. “Now is not the time to air differences” is the most seductive sentence in coalition politics. It is also how a coalition loses the capacity to course-correct. Kerensky’s government was forever insisting that the moment for reckoning with the radicals had not yet arrived. It never did arrive, because the logic that defers the reckoning is the same logic that makes the reckoning impossible.

For most of the last decade this argument could be waved away as alarmism. It is harder to wave away now, because the relevant faction has stopped merely influencing the Democratic Party and started capturing pieces of it outright.

The clearest case is New York. In 2025, Zohran Mamdani, a member of the Democratic Socialists of America who, until that year, was a backbench state assemblyman, won the Democratic mayoral primary in an upset over former governor Andrew Cuomo and went on to become the city’s mayor. He has been entirely candid about what he intends. “I was elected as a democratic socialist and I will govern as a democratic socialist,” he declared at his inauguration, adding that he would not abandon his principles “for fear of being deemed radical.” He was sworn in by Bernie Sanders, with Alexandria Ocasio-Cortez among the speakers, a tableau of the movement’s leadership presiding over its first command of America’s largest city.

What happened next is the part the analogy predicts. A figure of the activist left, having captured an institution, used it to discipline the moderates. In June 2026, Mamdani backed a slate of insurgent congressional candidates against sitting Democrats and swept. His endorsees ousted two incumbent congressmen: former comptroller Brad Lander unseated Representative Dan Goldman, and community organizer Darializa Avila Chevalier defeated Representative Adriano Espaillat, the chair of the Congressional Hispanic Caucus, while DSA-aligned assemblywoman Claire Valdez won an open Brooklyn-Queens seat. The mayor framed the project plainly: the goal was to elect “better Democrats.” Party leadership, by multiple accounts, was unsettled. It did not matter. The movement supplies the energy, the volunteers, and the primary electorate; the establishment supplies disapproving anonymous quotes to reporters. That is not a balance of power. That is a rout in slow motion.

Ocasio-Cortez herself offers a subtler illustration of the same gravitational pull. She was strategically cautious in 2026, declining to endorse the marquee House races, but she put her weight behind a slate of democratic-socialist candidates further down the ballot, building the bench. The vanguard does not always charge the front line. Sometimes it simply colonizes the farm system, race by race, until the moderates wake up to discover that the next generation of the party was selected without them.

## The Question Moderates Keep Declining to Answer

The Mamdani movement has been shadowed, from the campaign through the mayoralty, by sustained accusations of antisemitism. These are not fringe complaints. They came from the Anti-Defamation League, whose chief executive called the slogan “globalize the intifada” an explicit call for violence; from the United States Holocaust Memorial Museum; from Senator Kirsten Gillibrand; and from Jewish members of Congress, including Representative Dan Goldman, the very incumbent later defeated by a Mamdani-backed challenger running to his left on Israel. The flashpoints are a matter of record: Mamdani’s repeated refusal during the primary to condemn that slogan, which he characterized as a cry for Palestinian rights rather than a call to violence; his long association with the Boycott, Divestment, and Sanctions movement; his description of AIPAC and its supporters as “monsters”; and his pledge to arrest the Israeli prime minister.

The relevant point for this essay is not to adjudicate that charge. Mamdani has rejected it, saying it pained him to be called an antisemite, and later said he would “discourage” the contested phrase. The relevant point is how the broader coalition behaved. Confronted with a wing whose rhetoric a substantial part of their own base experienced as menacing, most Democratic leaders did what the Mensheviks did: they temporized. Hakeem Jeffries withheld his endorsement and suggested the candidate would need to “clarify” his position and then watched that candidate win anyway and then watched him pick off colleagues. The instinct to avoid a fight did not restrain the radical faction. It ceded ground to it. Each deferral made the next one cheaper. That is the Petrograd pattern stripped of its costume: not a coup, but a thousand small refusals to draw a line, each defensible on its own, fatal in aggregate.

What an Honest Analogy Must Concede

Here I must do what too many users of this comparison refuse to do: argue against my own thesis.

The disanalogies are substantial, and intellectual honesty requires stating them plainly rather than burying them.

First, the historical picture itself is more complicated than the morality tale allows. The Mensheviks were not undone merely by naïveté; they were undone by a catastrophic war, mass hunger, a collapsing army, and a state with no democratic tradition to fall back upon. The Provisional Government fell because Russia in 1917 had almost no institutional ballast. To borrow its lesson is to import a setting that bears little resemblance to a constitutional democracy with independent courts, federalism, a free press, and two and a half centuries of peaceful transfers of power.

Second, the contemporary Democratic left is, by any reasonable measure, democratic. It contests primaries, writes legislation, loses some fights and wins others, and accepts the outcomes. A faction that seeks power through elections and persuasion is categorically different from one that seeks it through a coup, however much one dislikes its program. Conflating the two is not analysis; it is a rhetorical maneuver designed to place ordinary intra-party disagreement beyond the bounds of legitimacy.

Third, the same structural argument can be aimed in the opposite direction with equal force. Every coalition has a wing that calls itself the responsible center and dismisses the energy of its activists as a liability—right up until that energy wins it elections. Movements that the establishment of their day deemed dangerously radical, from abolition to labor rights to civil rights, were vindicated precisely because moderates failed to suppress them. The “vanguard captures the moderates” story and the “moderates strangle necessary change” story are the same events told by opposite partisans. Which one you are living through is rarely obvious from the inside.

Fourth, and most simply: analogies persuade by feeling rather than by evidence, and the gap between “the deaths of millions” and a dispute over a party platform is a chasm that no rhetorical bridge should pretend to close. A comparison that ends in the Gulag is doing emotional work that the underlying facts do not support.

The Defensible Lesson

So what survives the scrutiny?

Not the equation of one party’s left with one of history’s great tyrannies, that does not survive and should not. What survives is narrower and more durable: *a coalition that will never confront its own most committed faction has surrendered the ability to govern itself.*

The genuine warning of 1917 is not about socialism and not about any one mayor. Radicalism is a permanent feature of democratic life and often its conscience. The warning is about the moderate temptation to treat every internal disagreement as disloyalty, to defer every reckoning in the name of unity, and to mistake the avoidance of a fight for the winning of one. A party that cannot tell its own activists “no” and cannot say where principle ends and a liability “begins” is not unified. It is merely captured and waiting to discover by whom.

The Mensheviks were not destroyed because they were insufficiently revolutionary or because they were insufficiently moderate. They were destroyed because they could not bring themselves to believe that the gravest challenge to their project might be sitting at their own table. That is a lesson worth taking seriously and worth holding loosely enough not to mistake every primary upset for a Bolshevik at the gate.
