Birthright Citizenship and the Politics of Constitutional Law (Part I)

Pranjal Drall and Samuel Moyn

There they go again. The litigation over Donald Trump’s executive order ending birthright citizenship has so far followed a familiar script. And liberals, especially lawyers among them, have played their appointed role, as if there were no other—even in the age of an openly reactionary Supreme Court majority.

First, liberals denied and even ridiculed the possibility of reading the Fourteenth Amendment Trump’s way. But subsequently, they have taken many steps to help normalize that very reading, by consenting to struggle on the terrain of their enemies.

After their loss in the general election produced Trump’s executive order, liberals hope to win at the Supreme Court. If they do, it will be because the politics of interpreting law favored their side, not because of the quality of their legal work. In cases such as this, legal arguments merely facilitate and rationalize outcomes reached for other reasons. Yet it is precisely here—on legal work, and most especially leaning into originalist methods and the virtues of American traditions—that the legalistic opponents of Trump’s new policy have concentrated exclusively.

Welcome to the spectacle of liberal constitutionalism in 2026, which obscures what we are doing, including to ourselves—a mistake for which we have paid an enormous price before.

In the face of a hegemonic and overwhelming discourse focused on what the Fourteenth Amendment really meant and means, we argue in this post for changing the subject. Unlike in the close parallel of NFIB v. Sebelius, where a similar campaign to radically shift constitutional meaning succeeded, liberals might win in Trump v. Barbara. If they do, it’s not going to be because they were “correct” about the law—even if they are. It will be because the political dynamics, having favored unexpected constitutional change unthinkable before in the prior case, stopped it in this one.

Therefore, the right question to ask all along, and openly, wasn’t just what the Constitution means. It is whether the constitutional terrain beckons as strategically opportune, and if so, why it could favor defenders of birthright citizenship in this case. Merely inquiring into what the Framers really believed and insisting one more time that the Constitution was born liberal, are inadequate—unless doing so is our best or sole option strategically.

Many years ago, Jack Balkin observed the great importance of analyzing constraints in legal interpretation. The central suggestion of the critical legal studies movement (of which he was then a member) was not that law is “indeterminate.” But the movement could reveal that ideological forces artificially constrained the range of interpretations of one or another piece of law. And it could better explain than rival frameworks how, under some conditions, the meaning of law could change radically. In subsequent work, Balkin highlighted the importance of who occupies important “nodes of power” in pushing for some meanings rather than others—and, of course, who has succeeded in the quest to control the apex sites of interpretation as the essential determinant of legal meaning when consensus breaks down.

In Balkin’s writings, the most famous example of these dynamics was how the Commerce Clause of the U.S. Constitution was, almost overnight, subjected to a campaign to undo the ideological consensus, that had held since the 1930s, that it imposed next to no limits on Congressional power. A reactionary claim that Barack Obama’s new health care plan in the Affordable Care Act was beyond the legislative authority granted by the Constitution gained traction and then, rather suddenly became the law of the land in NFIB v. Sebelius.

Once “off the wall,” in Balkin’s folksy redescription of the terms of his own earlier approach, the right-wing claim became credible or “on the wall.” Nothing about the Constitution changed. Old precedents remained in force. But enough elements of the ideological constraint were lifted that the new outcome become plausible. The result was devastating: though Chief Justice John Roberts found the saving construction of upholding much of Obama’s law under Congress’s tax power, millions of poor Americans lost the Medicaid expansion that Congress had decided to grant them.

The left pursues its own constitutional agendas of mainstreaming unlikely interpretive propositions, albeit with much less success—think of the attempt to dust off the Fourteenth Amendment’s second section in the litigation to keep Trump off the presidential ballot in 2024. But right now, it is urgent to address how Balkin’s model might help analyze the potential transformation of the amendment’s first section.

Yet legal discourse in the face of Trump’s Day-one executive order rescinding birthright citizenship has been overwhelmingly legalist, indeed originalist, without any hint of the ideological or political focus that Balkin’s model would demand. Liberals are LARPing, not strategizing—at least not openly.

If the executive order goes down, it is not going to be either because of the Constitution’s text or history, nor because of precedents that interpret either. It is because the ongoing right-wing campaign to undo a prior ideological consensus fails. And that reality raises the necessary question of whether playing along with—or into—the legalist and originalist strategies of lifting interpretive constraints of the right is the best move for the left, especially when those strategies on their own will not cast the die for the future of American citizenship.

In our next post, we chronicle the trajectory of this interpretation of the Fourteenth Amendment’s Citizenship Clause as a once fruitless project of constitutional transformation that found more fecund soil in our time—and how liberals and progressives have ended up helping to till it. A final post reflects on the politics of constitutional law, once the birthright citizenship saga is examined from a strategic, rather than legalist, point of view.
