Federalism and States' Rights: What Each Position Is Protecting

In June 2022, the Supreme Court's decision in Dobbs v. Jackson Women's Health Organization returned abortion regulation to the states. Within eighteen months, fourteen states had enacted near-total abortion bans, twelve others had expanded state-level abortion protections, and a woman named Kate Cox petitioned a Texas court for an emergency abortion for a fetus with a fatal diagnosis — a petition that moved through three courts in nine days while her medical situation deteriorated, ultimately requiring her to leave the state for care. Her story made visible what the federalism question actually means in human terms: the same medical procedure, performed by the same physician, for the same condition, is legal in California and a potential felony in Texas. Where you live now determines which constitutional order governs your body.

The federalism debate is often framed as a procedural argument about the Tenth Amendment and the proper allocation of powers between Washington and the states. That framing misses what is actually at stake. When California maintains vehicle emissions standards stricter than federal law, when Texas deploys state law enforcement at the border in conflict with federal immigration policy, when Colorado legalizes marijuana that remains a Schedule I substance under the Controlled Substances Act, when Illinois enacts sanctuary protections for undocumented residents while the federal government seeks to defund sanctuary cities — these are not dry arguments about constitutional structure. They are arguments about whose community gets to decide what kind of society it becomes, and whose rights depend on that answer.

By 2026, this debate has acquired a strange mirror quality: the same constitutional argument now appears on opposite sides of the political spectrum depending on which level of government is currently more hostile to a given interest. What is worth mapping is not who invokes federalism but what each position is actually trying to protect.

What constitutional federalism advocates are protecting

The proposition that self-governance is most meaningful when it operates at the level closest to the governed — that a community of 300 million people cannot make coherent collective decisions about questions on which it is genuinely and deeply divided, and that attempting to do so through federal law produces resentment, noncompliance, and democratic delegitimation. The argument is older than the Constitution itself; it is the argument the Anti-Federalists made against ratification, the argument Justice Louis Brandeis captured in his 1932 dissent in New State Ice Co. v. Liebmann when he wrote that "a single courageous state may, if its citizens choose, serve as a laboratory" for "novel social and economic experiments without risk to the rest of the country." The claim is not that states always make better decisions than the federal government. It is that distributed decision-making across fifty polities is more responsive to genuine diversity of values and circumstances than centralized decision-making that must produce a single national answer. When Vermont and Mississippi have different cultures, different economies, and different majoritarian views on, say, drug policy or land use or sex education, forcing them into identical frameworks means one will always feel governed against its will.

The structural argument that concentrating power in the federal government creates a single point of failure — that a federal government capable of imposing one community's values on another is equally capable of imposing the values of whoever wins the next presidential election on every community simultaneously. This argument draws directly on Madison's Federalist No. 51: the vertical division of power between state and federal government is one of the "auxiliary precautions" against tyranny, complementing the horizontal separation of legislative, executive, and judicial power. Randy Barnett of Georgetown Law School and other originalist scholars argue that the New Deal expansion of federal regulatory power effectively abolished the constitutional structure the Framers designed — that Commerce Clause jurisprudence since Wickard v. Filburn (1942) has given Congress authority over virtually any economic activity, leaving the Tenth Amendment's reservation of powers to the states as a near-nullity. What they are protecting is the constitutional design itself: the idea that enumerated federal powers are real limits, not rhetorical hedges.

The democratic legitimacy argument that state and local governments are more accountable to their constituents than the federal government — closer to voters, more responsive to local conditions, more easily thrown out when they govern badly. A state legislature makes decisions that affect a few million people who can reasonably monitor it; a federal regulatory agency makes decisions affecting three hundred and thirty million people through rulemaking processes that most citizens cannot practically access. The argument for federalism is partly an argument about the scale at which democracy actually functions: the town meeting is not a romantic anachronism but a real form of self-governance that national politics cannot replicate. What constitutional federalism advocates are protecting, ultimately, is the condition of possibility for meaningful self-rule — the idea that "we the people" governs something smaller than a continent.

What federal supremacy and civil rights advocates are protecting

The historical record that states' rights has been, throughout American history, the constitutional argument most reliably deployed to resist the extension of basic rights to excluded populations — that the same Tenth Amendment invoked today for drug legalization and abortion access was the constitutional argument for slavery, for segregation, for antimiscegenation laws, for poll taxes, and for the systematic exclusion of Black Americans from the social and economic life of the republic. This is not a tu quoque argument. It is a structural observation: when the question is whether a majority within a state can deny basic rights to a minority within that state, federalism functions as a mechanism for the localization of oppression. The Fourteenth Amendment — ratified in 1868 specifically to override state-level deprivation of equal protection and due process — is the constitutional response to this problem. The Civil Rights Act of 1964, the Voting Rights Act of 1965, the Americans with Disabilities Act of 1990: each of these is a federal override of state-level practices that were, at the moment of federal intervention, locally majoritarian and democratically enacted. What federal supremacy advocates are protecting is the principle that some rights are not negotiable by state majority — that a person's citizenship in the republic, not their residence in a particular state, determines their basic legal standing.

The economics argument that inter-state competition produces races to the bottom on labor standards, environmental regulation, and consumer protection — that when states compete to attract mobile capital, the pressure runs consistently toward lower wages, weaker worker protections, and less stringent environmental enforcement, not toward better governance. The "laboratories of democracy" metaphor imagines states experimenting and learning from each other. But this requires that the experiments being run are the ones states would choose absent competitive pressure. When states compete for corporate headquarters, Amazon distribution centers, or semiconductor fabs, the experiment being run is: how far will each state go in subsidizing capital and suppressing labor costs? Economic geographers like Richard Florida and legal scholars like Erwin Chemerinsky have documented that the outcomes of this competition tend to transfer wealth from workers and communities to mobile firms, with the strongest enforcement jurisdictions losing investment to weaker ones. Federal minimum standards — the National Labor Relations Act, the Clean Air Act, the Fair Labor Standards Act — are precisely the mechanism for preventing this race.

The equality-of-citizenship argument that the accident of birth geography should not determine the fundamental rights and legal protections to which a person is entitled — that a republic whose citizens' rights vary dramatically by state of residence is not governing a unified nation but a collection of semi-sovereign territories with differently valued citizenships. This argument is most pointed in the post-Dobbs moment: a woman in Louisiana has access to abortion care only if she can travel to Illinois or New Mexico, which requires money, time off work, childcare, and logistical capacity that is not equally distributed. The right exists on paper in Illinois and not in Louisiana, but the effective rights gap between a wealthy woman in Baton Rouge and a low-income woman in the same city is larger than the formal legal difference between the states. Federal civil rights advocates are protecting the proposition that equal citizenship requires at minimum equal access to fundamental rights — and that geographic inequality in basic rights is a form of constitutional failure, not a feature of constitutional design.

What competitive federalism advocates are protecting

Exit rights — the capacity of individuals, families, and businesses to leave jurisdictions that govern them badly and move to ones that govern them better, creating a competitive dynamic that disciplines state governments in ways that elections alone cannot. Charles Tiebout's 1956 paper "A Pure Theory of Local Expenditures" is the founding document of competitive federalism theory: when people can move between jurisdictions, they "vote with their feet" by choosing the package of public services and tax levels that matches their preferences. The result, on the Tiebout model, is efficient provision of public goods calibrated to citizen preferences rather than bureaucratic discretion. This is the argument behind the population shifts from California and New York to Texas and Florida over the past decade: that high-tax, high-regulation states lose residents to lower-tax, lower-regulation states, and that this competitive pressure disciplines both kinds of state to deliver value. What competitive federalism advocates are protecting is the anti-monopoly logic of jurisdictional diversity: no single government can become entrenched and unresponsive when citizens have options.

The argument for policy experimentation — that genuine uncertainty about which approaches to governance problems actually work means that distributed experimentation across fifty states produces more information about what works than any single national policy can. This is the empirical case for federalism, distinct from the constitutional or exit-rights cases: Massachusetts's individual health insurance mandate became the model for the Affordable Care Act; Oregon's drug decriminalization generated evidence about harm reduction that shifted national policy debate; Wisconsin's welfare reform under Governor Tommy Thompson was piloted before being incorporated into the 1996 federal welfare reform. States as laboratories is not only a metaphor. It is a claim about epistemic humility: we do not know in advance which policy interventions work, and a federal system that allows state-level variation generates the evidence needed to learn. What competitive federalism advocates are protecting is the capacity of the system to learn from its own experiments rather than locking in single national answers before the evidence is in.

What progressive federalism advocates are protecting

The capacity of state and local governments to exceed federal floors — to protect rights and enforce standards more robustly than federal law requires, even when a hostile federal administration is actively trying to roll back protections. This is the position that has migrated most dramatically across the partisan divide. In 2016, the same conservatives who invoked states' rights to resist the ACA's Medicaid expansion were arguing that California's sanctuary city policies violated federal supremacy. In 2025, the same progressives who had championed federal civil rights enforcement were invoking state sovereignty to resist federal immigration enforcement in their jurisdictions. The underlying principle — that state-level authority provides a buffer against federal overreach — did not change. The political valence of who was being protected from what changed.

The concrete protection of people whom the federal government has decided to exclude from its protection — immigrants in sanctuary jurisdictions, trans youth in states with affirmative gender-affirming care protections, reproductive-age people in states that have codified abortion rights, workers in states with stronger labor protections than federal law provides. California's AB 1305 and its climate disclosure requirements exceed SEC rules; Washington State's My Health My Data Act regulates health data collection by non-HIPAA-covered entities in ways federal law does not; Colorado's POWR Act strengthened workplace discrimination protections beyond Title VII's reach. Each of these represents a state using its residual authority to protect people whom federal law either does not reach or has actively left exposed. Progressive federalism advocates are protecting a practical resource: the ability to use state-level majorities to build policy infrastructure that can survive federal elections and provide real protection to real people in the interval between moments of federal alignment.

The anti-nationalization-of-politics argument that when every consequential policy question is resolved at the federal level, every federal election becomes existentially high-stakes — and that returning some consequential decisions to states reduces the total prize at stake in any single election, making democratic politics less catastrophic when your side loses. This argument, made by scholars including Heather Gerken of Yale Law School in her work on "dissenting by deciding," holds that federalism is not only a mechanism for protecting conservative or libertarian interests — it is a structural feature that makes pluralistic coexistence possible across genuine value disagreement. When Washington, D.C. decides everything, losing a presidential election means losing access to the entire machinery of governance. When states retain meaningful authority, losing federal power does not mean losing all power. Progressive federalism advocates are protecting the political diversity that makes democratic losers willing to stay in the game.
