Jonah Goldberg writes in the LAT:
Marco Rubio is the only adult left in the room
Finally free from the demands of being Chief Archivist of the United States, Secretary of State, National Security Advisor and unofficial Viceroy of Venezuela, Marco Rubio made his way to the Munich Security Conference last weekend to deliver a major address.
I shouldn’t make fun. Rubio, unlike so many major figures in this administration, is a bona fide serious person. Indeed, that’s why President Trump keeps piling responsibilities on him. Rubio knows what he’s talking about and cares about policy. He is hardly a free agent; Trump is still president after all. But in an administration full of people willing to act like social media trolls, Rubio stands out for being serious. And I welcome that.
Jonah was making fun? Who knew?
I find it a tad much for the author of Liberal Fascism to decree who the adults are.
Jonah Goldberg built his reputation with Liberal Fascism, a book that stretched categories for polemical effect. It wasn’t careful scholarship. It was a ludicrous culture-war brief designed to signal in-group loyalty and moral clarity. That worked in its moment for the willingly gullible, but it undercuts any later claim to be the referee of seriousness.
When someone who made his name flattening complex political traditions into a branding exercise starts handing out “adult in the room” badges, it feels rich. The posture shifts from provocateur to school principal without an intervening reckoning.
There’s also a category error. “Serious” used to mean analytically rigorous, empirically grounded, willing to revise beliefs. In pundit usage today, it usually means fluent in institutional language and emotionally aligned with elite norms. Liberal Fascism was not serious in the first sense. It was very serious in the second. It reassured a coalition that it was morally superior and intellectually awake.
So when Goldberg anoints adults, he’s really saying who feels safe to his class. That’s not maturity. That’s familiarity.
This column exemplifies the prestige system talking past itself. The people who still care about that credentialing ritual are mostly the ones performing it.
When elites or mainstream commentators say someone is the “adult in the room,” they’re not making a neutral psychological observation. They’re doing alliance work.
The phrase does a few things at once.
First, it frames politics as a maturity hierarchy. One side is impulsive, emotional, reckless. The other side is sober, policy-minded, responsible. That is a status move. “Adult” is coded as competent, rational, managerial. It flatters the coalition that sees itself as technocratic and steady.
Second, it signals reassurance to anxious allies. When a coalition feels embarrassed by its own leader or style, it elevates someone inside the camp as the “serious person.” That keeps donors, staffers, and institutional actors calm. It says: don’t worry, there are still people who speak our language of briefings, memos, and interagency process.
Third, it protects the writer’s own identity. Calling someone “the adult” tells readers that the columnist belongs to the grown-up world of policy seriousness. It is a credentialing move. Serious people recognize other serious people.
In the case of Marco Rubio and Jonah Goldberg, this language is especially revealing. Goldberg built his career defending a form of conservatism that prizes institutional continuity, intellectual coherence, and policy depth. Trump-era politics disrupted that style. So when he says Rubio is “bona fide serious,” he’s not just praising Rubio. He’s defending a model of conservatism that values white papers over viral posts.
From an alliance theory perspective, “adult in the room” is a coalition stabilizer. It reassures business conservatives, think tankers, and foreign policy hands that their norms still have representation. It’s less about who actually holds power and more about who embodies the older prestige code.
Why does it sound silly? Because “serious” is a fuzzy word. It often means “speaks in institutional tones that I recognize.” It does not necessarily mean wise, effective, or electorally attuned. Many voters see the so-called serious class as having misread the country for years. So when a pundit praises someone as an adult, it can sound like self-congratulation from a shrinking tribe.
There’s also a deeper tension. Modern media rewards performative combat. Social media rewards speed and edge. If an administration rises through that ecosystem, calling one member “the adult” can sound like a nostalgic attempt to re-center an older prestige order that no longer dominates.
Bottom line: “adult in the room” is not a diagnosis. It’s a status signal. It marks who counts as legitimate inside a particular elite network. Whether that network still maps onto political reality is the real question.
Written with AI: The concept of “adults in the room” is a long-standing political trope used by members of the political establishment and the media to distinguish between figures they perceive as stable and those they see as disruptive. When pundits like Jonah Goldberg use this language, they are employing a specific rhetorical framework to signal competence, predictability, and adherence to institutional norms.
In the context of the Washington establishment, labeling someone like Marco Rubio as a “serious person” usually refers to a set of specific characteristics:
Policy Orientation: Engaging with the technical details of legislation and diplomacy rather than focusing primarily on cultural grievances or social media performance.
Institutionalism: A respect for traditional structures of power, such as the State Department, the intelligence community, and international alliances like NATO.
Decorum: Using formal, conciliatory language that aligns with the professional standards of the “ruling class,” as opposed to the more combative or populist rhetoric used by “social media trolls.”
In Goldberg’s recent column, he points to Rubio’s speech at the Munich Security Conference as evidence of this seriousness. By making a coherent, policy-heavy argument—even if Goldberg disagree with parts of it—Rubio provides a contrast to figures like Vice President JD Vance, whom Goldberg characterizes as performing for an online audience rather than engaging in traditional statecraft.
Media elites and “Mainstream Media” (MSM) outlets use the “adult” metaphor because it establishes a hierarchy of governance. This framing serves several purposes:
Signal of Stability: It reassures international allies, financial markets, and donors that there is a “steady hand” within an otherwise unpredictable administration.
Gatekeeping: By defining “seriousness” as “adherence to the status quo,” the establishment can marginalize populist ideas by framing them as immature or “unserious,” regardless of the actual substance of the arguments.
Shared Language: It creates a category for politicians who are willing to speak the “language of the room”—the jargon and protocols of the D.C. elite—which allows for a level of predictability that institutions crave.
Many find this framing “silly” or intellectually dishonest. Critics of the trope often argue that:
The “Serious” Failures: Many of the most “serious” people in the room over the last thirty years were the architects of major policy failures, such as the Iraq War or the 2008 financial crisis. This suggests that “seriousness” is often a measure of conformity rather than actual wisdom or success.
Performative Maturity: Some observers argue that Rubio and others are labeled “adults” simply because they use a more professional tone, even when they are executing the exact same policies as the “trolls” they are being contrasted with.
Elitism: The “adult/child” binary is inherently patronizing. It suggests that political disagreements are not about fundamentally different visions for the country, but rather about a lack of maturity on one side.
By calling Rubio the “only adult left,” Goldberg is attempting to carve out a space for traditional conservatism within a MAGA-led administration. For Goldberg, Rubio represents a bridge back to a style of governance that values expertise and international commitments, even if he is ultimately serving a president who often treats those same institutions with skepticism.
