The Erosion of Dual Sovereignty

The United States was fundamentally engineered as a compound republic — a union forged by the explicit will of thirteen sovereign colonies. The foundational compact that bound them, the United States Constitution, was meticulously drafted to preserve this pre-existing sovereignty while granting the newly formed federal government only specific, enumerated powers. This article examines the structural erosion of that original architecture across constitutional, administrative, and sociological dimensions — and specifies what serious recovery would require.

The Original Architecture of Dual Sovereignty

Prior to the ratification of the Constitution, the thirteen colonies operated effectively as independent nations, possessing their own elected heads of state, legislative congresses, and distinct judiciaries, unified temporarily for a common good. The Constitution was drafted to preserve this pre-existing sovereignty while granting the federal government only specific, enumerated powers necessary for national defense, foreign policy, and the facilitation of interstate commerce. Federalism — the sharing of powers between the states and the national government — was viewed as the most critical structural feature of the U.S. constitutional order.

As James Madison noted in Federalist No. 51, the architecture was designed so that the different governments will control each other, at the same time that each will be controlled by itself. The Tenth Amendment, ratified December 15, 1791, codified the doctrine of dual sovereignty with unambiguous language: The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.

At the Constitutional Convention of 1787, the preservation of state sovereignty was of paramount concern. The framers initially voted unanimously (10-0) against the inclusion of a comprehensive Bill of Rights — not from disdain for civil liberties, but from the explicit, structural presumption that the federal government was strictly limited to its enumerated powers. From the perspective of certain framers, including Hamilton, listing specific rights was deemed dangerous because it could imply that the federal government possessed inherent authority to regulate those areas unless explicitly forbidden.

The Three Erosion Mechanisms

The structural erosion of dual sovereignty has occurred through three primary mechanisms operating across different time horizons. Each is independently consequential. Together, they have produced a federal architecture that bears only nominal resemblance to the one ratified in 1789.

Mechanism One: The Incorporation Doctrine

The Fourteenth Amendment, ratified in 1868 in the wake of the Civil War, was the first major constitutional reorganization of the federal-state balance. Its due process and equal protection clauses provided the textual basis for the incorporation doctrine — the gradual application of Bill of Rights protections to state governments. The doctrine developed slowly through Supreme Court jurisprudence over the twentieth century, with most major Bill of Rights protections incorporated against the states between 1925 (Gitlow v. New York, free speech) and 2010 (McDonald v. Chicago, Second Amendment).

The incorporation doctrine was, in many respects, a corrective response to the Civil War — an acknowledgment that state sovereignty had been used to perpetuate slavery and could not be left structurally unchecked. But the doctrine's expansion beyond its original Reconstruction-era purpose progressively reduced the structural autonomy of state governments to organize their internal affairs differently from federal preference. Whether this expansion was net beneficial or net harmful depends on which historical period and which policy domain one examines. The structural fact is that it represents a substantial reduction in the dual sovereignty originally codified.

Mechanism Two: The New Deal Commerce Clause Expansion

The second major erosion occurred through the New Deal-era reinterpretation of the Commerce Clause. Wickard v. Filburn (1942) held that a farmer's cultivation of wheat for personal consumption was subject to federal regulation under the Commerce Clause because, in aggregate, such cultivation could affect interstate commerce. The decision effectively eliminated any meaningful limit on what could be regulated as interstate commerce, since virtually any economic activity, in aggregate, has some effect on interstate markets.

The post-New Deal Commerce Clause has been the constitutional basis for federal regulation of agriculture, environmental protection, civil rights, healthcare, and countless other domains that the framers would have considered firmly within state jurisdiction. Whether the policy outcomes are desirable is a separate question from the structural one. The structural fact is that the post-1942 federal government operates under a Commerce Clause that bears little resemblance to the limited interstate-coordination provision the framers ratified.

Mechanism Three: The Administrative State

The third mechanism, operating largely outside constitutional doctrine, is the growth of the federal administrative state. Beginning with the Interstate Commerce Commission (1887) and accelerating through the New Deal, the post-WWII era, and the regulatory expansion of the 1960s and 1970s, federal agencies have become the primary venue in which federal authority is actually exercised. Congress passes broad enabling statutes; agencies promulgate the detailed regulations that constitute the operational law; courts review the regulations under deferential standards (chief among them Chevron deference, recently weakened by Loper Bright Enterprises v. Raimondo in 2024).

The administrative state is significant for federalism because it operates with minimal sensitivity to state-federal balance. Federal agencies promulgate national rules that preempt state experimentation, even in domains where the underlying statutory authority is ambiguous about preemption. The result is a federal architecture in which the day-to-day operational law that affects citizens' lives is generated primarily by federal administrative action rather than by elected state or federal legislatures.

The Sociological Dimension: Subsidiarity and Civic Capacity

The constitutional and administrative erosions have produced a sociological consequence the framers anticipated and feared. Tocqueville observed that the strength of American self-government in the 1830s depended on the dense layering of local civic institutions in which citizens directly participated — town meetings, voluntary associations, county boards, parish vestries. These institutions were not just policy mechanisms; they were schools of self-government in which the capacity for collective decision-making was developed and maintained.

The principle Tocqueville described, later formalized in Catholic social teaching as subsidiarity, holds that decisions should be made at the smallest competent level — only those decisions that genuinely cannot be handled locally should be elevated to higher authority. Subsidiarity is not a partisan principle. It appears in conservative defenses of federalism and progressive defenses of community organizing alike. It is structural: it reflects the empirical observation that civic capacity, like any other capacity, atrophies when it is not exercised.

The progressive centralization of decision-making at the federal and federal-administrative level has the predictable sociological consequence of atrophying state, local, and civic capacity for self-government. The citizen whose meaningful policy decisions are all made in Washington has less reason to engage in the local institutions that previously developed civic capacity. The local institutions, deprived of meaningful authority, become harder to recruit competent participants for. The cycle compounds: as civic capacity atrophies, more decisions migrate upward, which further atrophies civic capacity.

What Recovery Would Actually Require

Serious recovery of dual sovereignty would require structural changes across all three erosion dimensions, not merely rhetorical commitment to states' rights. The political coalition currently most associated with federalism rhetoric has frequently expanded federal authority when it served its policy preferences. Recovery is not a partisan question. It is a structural question that any coalition would have to address coherently.

Constitutional dimension. Selective de-incorporation of certain Bill of Rights provisions where the original Reconstruction-era purpose has been satisfied. Restoration of meaningful Commerce Clause limits — distinguishing genuine interstate economic activity from local activity with marginal interstate effects. Revival of the major questions doctrine, which requires explicit congressional authorization for agency action of major economic and political significance. Administrative dimension. The Loper Bright weakening of Chevron deference is a step in this direction. Further reform would include strengthening the requirement for actual congressional authorization (rather than agency self-authorization through expansive statutory interpretation), narrowing federal preemption of state regulation, and strengthening the role of state attorneys general in challenging federal administrative overreach. Sociological dimension. Active investment in the local civic institutions that subsidiarity requires — schools, libraries, community organizations, local government bodies, voluntary associations. Without civic capacity at the local level, structural reforms at the constitutional and administrative levels will not produce functional federalism. The civic substrate must be rebuilt alongside the legal architecture.

The state-federal balance is not a constitutional curiosity. It is the structural feature that determines whether self-government is possible at scale. A federation in which all meaningful decisions are made centrally is, operationally, not a federation. Recovery of dual sovereignty is therefore not a backward-looking nostalgia for an earlier constitutional moment. It is the forward-looking question of whether a free society of three hundred and forty million people can govern itself democratically — or whether scale itself has made meaningful self-government structurally impossible. The framers thought it was possible. The structural design they ratified was their answer. Whether their answer can be recovered, adapted, or replaced is the open question of contemporary American constitutional politics.
