JUSTICE O'CONNOR delivered the opinion of the Court. These cases implicate one of our Nation's newest problems of public policy and perhaps our oldest question of constitutionallaw. The public policy issue involves the disposal of radioactive waste: In these cases, we address the constitutionality of three provisions of the Low-Level Radioactive Waste Policy Amendments Act of 1985, Pub. L. 99-240, 99 Stat. 1842, 42 U. S. C. § 2021bet seq.The constitutional question is as old as the Constitution: It consists of discerning the proper division of authority between the Federal Government and the States. We conclude that while Congress has substantial power under the Constitution to encourage the States to provide for the disposal of the radioactive waste generated within their borders, the Constitution does not confer upon Congress the ability simply to compel the States to do so. We therefore find that only two of the Act's three provisions at issue are consistent with the Constitution's allocation of power to the Federal Government.

We live in a world full of low level radioactive waste. Radioactive material is present in luminous watch dials, smoke alarms, measurement devices, medical fluids, research materials, and the protective gear and construction materials used by workers at nuclear power plants. Low level radioactive waste is generated by the Government, by hospitals, by research institutions, and by various industries. The waste must be isolated from humans for long periods of time,

Briefs of amici curiae were filed for the State of Connecticut by Richard Blumenthal, Attorney General, and Aaron S. Bayer, Deputy Attorney General; for the State of Michigan by Frank J. Kelley, Attorney General, Gay Secor Hardy, Solicitor General, and Thomas L. Casey, A. Michael Leffler, and John C. Scherbarth, Assistant Attorneys General; and for US Ecology, Inc., by Irwin Goldbloom. often for hundreds of years. Millions of cubic feet of low level radioactive waste must be disposed of each year. See App. 110a-111a; Berkovitz, Waste Wars: Did Congress "Nuke" State Sovereignty in the Low-Level Radioactive Waste Policy Amendments Act of 1985?, 11 Harv. Envtl. L. Rev. 437, 439-440 (1987).
Our Nation's first site for the land disposal of commercial low level radioactive waste opened in 1962 in Beatty, Nevada. Five more sites opened in the following decade: Maxey Flats, Kentucky (1963), West Valley, New York (1963), Hanford, Washington (1965), Sheffield, Illinois (1967), and Barnwell, South Carolina (1971). Between 1975 and 1978, the Illinois site closed because it was full, and water management problems caused the closure of the sites in Kentucky and New York. As a result, since 1979 only three disposal sitesthose in Nevada, Washington, and South Carolina-have been in operation. Waste generated in the rest of the country must be shipped to one of these three sites for disposal. See Low-Level Radioactive Waste Regulation 39-40 (M. Burns ed. 1988).
In 1979, both the Washington and Nevada sites were forced to shut down temporarily, leaving South Carolina to shoulder the responsibility of storing low level radioactive waste produced in every part of the country. The Governor of South Carolina, understandably perturbed, ordered a 50% reduction in the quantity of waste accepted at the Barnwell site. The Governors of Washington and Nevada announced plans to shut their sites permanently. App. 142a, 152a.
Faced with the possibility that the Nation would be left with no disposal sites for low level radioactive waste, Congress responded by enacting the Low-Level Radioactive Waste Policy Act, Pub. L. 96-573, 94 Stat. 3347. Relying largely on a report submitted by the National Governors' Association, see App. 105a-141a, Congress declared a federal policy of holding each State "responsible for providing for the availability of capacity either within or outside the State for the disposal of low-level radioactive waste generated within its borders," and found that such waste could be disposed of "most safely and efficiently… on a regional basis." § 4(a)(1), 94 Stat. 3348. The 1980 Act authorized States to enter into regional compacts that, once ratified by Congress, would have the authority beginning in 1986 to restrict the use of their disposal facilities to waste generated within member States. § 4(a)(2)(B), 94 Stat. 3348. The 1980 Act included no penalties for States that failed to participate in this plan.
By 1985, only three approved regional compacts had operational disposal facilities; not surprisingly, these were the compacts formed around South Carolina, Nevada, and Washington, the three sited States. The following year, the 1980 Act would have given these three compacts the ability to exclude waste from nonmembers, and the remaining 31 States would have had no assured outlet for their low level radioactive waste. With this prospect looming, Congress once again took up the issue of waste disposal. The result was the legislation challenged here, the Low-Level Radioactive Waste Policy Amendments Act of 1985.
The 1985 Act was again based largely on a proposal submitted by the National Governors' Association. In broad outline, the Act embodies a compromise among the sited and unsited States. The sited States agreed to extend for seven years the period in which they would accept low level radioactive waste from other States. In exchange, the unsited States agreed to end their reliance on the sited States by 1992.
The mechanics of this compromise are intricate. The Act directs: "Each State shall be responsible for providing, either by itself or in cooperation with other States, for the disposal of… low-level radioactive waste generated within the State," 42 U. S. C. § 2021c(a)(1)(A), with the exception of certain waste generated by the Federal Government, §§ 2021c(a)(1)(B), 2021c(b). The Act authorizes States to "enter into such [interstate] compacts as may be necessary to provide for the establishment and operation of regional disposal facilities for low-level radioactive waste." § 2021d(a)(2). For an additional seven years beyond the period contemplated by the 1980 Act, from the beginning of 1986 through the end of 1992, the three existing disposal sites "shall make disposal capacity available for low-level radioactive waste generated by any source," with certain exceptions not relevant here. § 2021e(a)(2). But the three States in which the disposal sites are located are permitted to exact a graduated surcharge for waste arriving from outside the regional compact-in 1986-1987, $10 per cubic foot; in 1988-1989, $20 per cubic foot; and in 1990-1992, $40 per cubic foot. § 2021e(d)(1). After the 7-year transition period expires, approved regional compacts may exclude radioactive waste generated outside the region. § 2021d(c).
The Act provides three types of incentives to encourage the States to comply with their statutory obligation to provide for the disposal of waste generated within their borders.
1. Monetary incentives. One quarter of the surcharges collected by the sited States must be transferred to an escrow account held by the Secretary of Energy. § 2021e (d)(2)(A). The Secretary then makes payments from this account to each State that has complied with a series of deadlines. By July 1, 1986, each State was to have ratified legislation either joining a regional compact or indicating an intent to develop a disposal facility within the State. §§ 2021e (e)(1)(A),2021e(d)(2)(B)(i). By January 1, 1988, each unsited compact was to have identified the State in which its facility would be located, and each compact or stand-alone State was to have developed a siting plan and taken other identified steps. §§ 2021e(e)(1)(B), 2021e(d)(2)(B)(ii). By January 1, 1990, each State or compact was to have filed a complete application for a license to operate a disposal facility, or the Governor of any State that had not filed an application was to have certified that the State would be capable of disposing of all waste generated in the State after 1992. §§ 2021e (e)(l)(C), 2021e(d)(2)(B)(iii). The rest of the account is to be paid out to those States or compacts able to dispose of all low level radioactive waste generated within their borders by January 1, 1993. § 2021e(d)(2)(B)(iv). Each State that has not met the 1993 deadline must either take title to the waste generated within its borders or forfeit to the waste generators the incentive payments it has received. § 2021e(d)(2)(C).
2. Access incentives. The second type of incentive involves the denial of access to disposal sites. States that fail to meet the July 1986 deadline may be charged twice the ordinary surcharge for the remainder of 1986 and may be denied access to disposal facilities thereafter. § 2021e(e)(2) (A). States that fail to meet the 1988 deadline may be charged double surcharges for the first half of 1988 and quadruple surcharges for the second half of 1988, and may be denied access thereafter. § 2021e(e)(2)(B). States that fail to meet the 1990 deadline may be denied access. § 2021e (e)(2)(C). Finally, States that have not filed complete applications by January 1, 1992, for a license to operate a disposal facility, or States belonging to compacts that have not filed such applications, may be charged triple surcharges. §§ 2021e(e)(1)(D), 2021e(e)(2)(D).
3. The take title provision. The third type of incentive
is the most severe. The Act provides:"If a State (or, where applicable, a compact region) in which low-level radioactive waste is generated is unable to provide for the disposal of all such waste generated within such State or compact region by January 1, 1996, each State in which such waste is generated, upon the request of the generator or owner of the waste, shall take title to the waste, be obligated to take possession of the waste, and shall be liable for all damages directly or indirectly incurred by such generator or owner as a consequence of the failure of the State to take possession
of the waste as soon after January 1, 1996, as the generator or owner notifies the State that the waste is available for shipment." § 2021e(d)(2)(C).
These three incentives are the focus of petitioners' constitutional challenge.
In the seven years since the Act took effect, Congress has approved nine regional compacts, encompassing 42 of the States. All six unsited compacts and four of the unaffiliated States have met the first three statutory milestones. Brief for United States 10, n. 19; id., at 13, n. 25.
New York, a State whose residents generate a relatively large share of the Nation's low level radioactive waste, did not join a regional compact. Instead, the State complied with the Act's requirements by enacting legislation providing for the siting and financing of a disposal facility in New York. The State has identified five potential sites, three in Allegany County and two in Cortland County. Residents of the two counties oppose the State's choice of location. App. 29a-30a, 66a-68a.
Petitioners-the State of New York and the two counties-filed this suit against the United States in 1990. They sought a declaratory judgment that the Act is inconsistent with the Tenth and Eleventh Amendments to the Constitution, with the Due Process Clause of the Fifth Amendment, and with the Guarantee Clause of Article IV of the Constitution. The States of Washington, Nevada, and South Carolina intervened as defendants. The District Court dismissed the complaint. 757 F. Supp. 10 (NDNY 1990). The Court of Appeals affirmed. 942 F.2d 114 (CA2 1991). Petitioners have abandoned their due process and Eleventh Amendment claims on their way up the appellate ladder; as the cases stand before us, petitioners claim only that the Act is inconsistent with the Tenth Amendment and the Guarantee Clause. II A
In 1788, in the course of explaining to the citizens of New York why the recently drafted Constitution provided for federal courts, Alexander Hamilton observed: "The erection of a new government, whatever care or wisdom may distinguish the work, cannot fail to originate questions of intricacy and nicety; and these may, in a particular manner, be expected to flow from the the establishment of a constitution founded upon the total or partial incorporation of a number of distinct sovereignties." The Federalist No. 82, p. 491 (C. Rossiter ed. 1961). Hamilton's prediction has proved quite accurate. While no one disputes the proposition that "[t]he Constitution created a Federal Government of limited powers," Gregory v. Ashcroft, 501 U. S. 452, 457 (1991); and while the Tenth Amendment makes explicit that "[t]he 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"; the task of ascertaining the constitutionalline between federal and state power has given rise to many of the Court's most difficult and celebrated cases. At least as far back as Martin v. Hunter's Lessee, 1 Wheat. 304, 324 (1816), the Court has resolved questions "of great importance and delicacy" in determining whether particular sovereign powers have been granted by the Constitution to the Federal Government or have been retained by the States.
These questions can be viewed in either of two ways. In some cases the Court has inquired whether an Act of Congress is authorized by one of the powers delegated to Congress in Article I of the Constitution. See, e. g., Perez v. United States, 402 U. S. 146 (1971); McCulloch v. Maryland, 4 Wheat. 316 (1819). In other cases the Court has sought to determine whether an Act of Congress invades the province of state sovereignty reserved by the Tenth Amendment. See, e. g., Garcia v. San Antonio Metropolitan Transit Au thority, 469 U. S. 528 (1985); Lane County v. Oregon, 7 Wall. 71 (1869). In a case like these, involving the division of authority between federal and state governments, the two inquiries are mirror images of each other. If a power is delegated to Congress in the Constitution, the Tenth Amendment expressly disclaims any reservation of that power to the States; if a power is an attribute of state sovereignty reserved by the Tenth Amendment, it is necessarily a power the Constitution has not conferred on Congress. See United States v. Oregon, 366 U. S. 643, 649 (1961); Case v. Bowles, 327 U. S. 92, 102 (1946); Oklahoma ex rel. Phillips v. Guy F. Atkinson Co., 313 U. S. 508, 534 (1941).
It is in this sense that the Tenth Amendment "states but a truism that all is retained which has not been surrendered." United States v. Darby, 312 U. S. 100, 124 (1941). As Justice Story put it, "[t]his amendment is a mere affirmation of what, upon any just reasoning, is a necessary rule of interpreting the constitution. Being an instrument of limited and enumerated powers, it follows irresistibly, that what is not conferred, is withheld, and belongs to the state authorities." 3 J. Story, Commentaries on the Constitution of the United States 752 (1833). This has been the Court's consistent understanding: "The States unquestionably do retai[n] a significant measure of sovereign authority… to the extent that the Constitution has not divested them of their original powers and transferred those powers to the Federal Government." Garcia v. San Antonio Metropolitan Transit Authority, supra, at 549 (internal quotation marks omitted).
Congress exercises its conferred powers subject to the limitations contained in the Constitution. Thus, for example, under the Commerce Clause Congress may regulate publishers engaged in interstate commerce, but Congress is constrained in the exercise of that power by the First Amendment. The Tenth Amendment likewise restrains the power of Congress, but this limit is not derived from the text of the Tenth Amendment itself, which, as we have discussed, is essentially a tautology. Instead, the Tenth Amendment confirms that the power of the Federal Government is subject to limits that may, in a given instance, reserve power to the States. The Tenth Amendment thus directs us to determine, as in this case, whether an incident of state sovereignty is protected by a limitation on an Article I power.
The benefits of this federal structure have been extensively cataloged elsewhere, see, e. g., Gregory v. Ashcroft, supra, at 457-460; Merritt, The Guarantee Clause and State Autonomy: Federalism for a Third Century, 88 Colum. L. Rev. 1, 3-10 (1988); McConnell, Federalism: Evaluating the Founders' Design, 54 U. Chi. L. Rev. 1484, 1491-1511 (1987), but they need not concern us here. Our task would be the same even if one could prove that federalism secured no advantages to anyone. It consists not of devising our preferred system of government, but of understanding and applying the framework set forth in the Constitution. "The question is not what power the Federal Government ought to have but what powers in fact have been given by the people." United States v. Butler, 297 U. S. 1, 63 (1936).
This framework has been sufficiently flexible over the past two centuries to allow for enormous changes in the nature of government. The Federal Government undertakes activities today that would have been unimaginable to the Framers in two senses; first, because the Framers would not have conceived that any government would conduct such activities; and second, because the Framers would not have believed that the Federal Government, rather than the States, would assume such responsibilities. Yet the powers conferred upon the Federal Government by the Constitution were phrased in language broad enough to allow for the expansion of the Federal Government's role. Among the provisions of the Constitution that have been particularly important in this regard, three concern us here.
First, the Constitution allocates to Congress the power "[t]o regulate Commerce… among the several States." Art. I, § 8, cl. 3. Interstate commerce was an established feature of life in the late 18th century. See, e. g., The Federalist No. 42, p. 267 (C. Rossiter ed. 1961) ("The defect of power in the existing Confederacy to regulate the commerce between its several members [has] been clearly pointed out by experience"). The volume of interstate commerce and the range of commonly accepted objects of government regulation have, however, expanded considerably in the last 200 years, and the regulatory authority of Congress has expanded along with them. As interstate commerce has become ubiquitous, activities once considered purely local have come to have effects on the national economy, and have accordingly come within the scope of Congress' commerce power. See, e. g., Katzenbach v. McClung, 379 U. S. 294 (1964); Wickard v. Filburn, 317 U. S. 111 (1942).
Second, the Constitution authorizes Congress "to pay the Debts and provide for the… general Welfare of the United States." Art. I, § 8, cl. 1. As conventional notions of the proper objects of government spending have changed over the years, so has the ability of Congress to "fix the terms on which it shall disburse federal money to the States." Pennhurst State School and Hospital v. Halderman, 451 U. S. 1, 17 (1981). Compare, e. g., United States v. Butler, supra, at 72-75 (spending power does not authorize Congress to subsidize farmers), with South Dakota v. Dole, 483 U. S. 203 (1987) (spending power permits Congress to condition highway funds on States' adoption of minimum drinking age). While the spending power is "subject to several general restrictions articulated in our cases," id., at 207, these restrictions have not been so severe as to prevent the regulatory authority of Congress from generally keeping up with the growth of the federal budget.
The Court's broad construction of Congress' power under the Commerce and Spending Clauses has of course been guided, as it has with respect to Congress' power generally, by the Constitution's Necessary and Proper Clause, which authorizes Congress "[t]o make all Laws which shall be necessary and proper for carrying into Execution the foregoing Powers." U. S. Const., Art. I, § 8, cl. 18. See, e. g., Legal Tender Case, 110 U. S. 421, 449-450 (1884); McCulloch v. Maryland, 4 Wheat., at 411-421.
Finally, the Constitution provides that "the Laws of the United States… shall be the supreme Law of the Land… any Thing in the Constitution or Laws of any State to the Contrary notwithstanding." U. S. Const., Art. VI, cl. 2. As the Federal Government's willingness to exercise power within the confines of the Constitution has grown, the authority of the States has correspondingly diminished to the extent that federal and state policies have conflicted. See, e. g., Shaw v. Delta Air Lines, Inc., 463 U. S. 85 (1983). We have observed that the Supremacy Clause gives the Federal Government "a decided advantage in thee] delicate balance" the Constitution strikes between state and federal power. Gregory v. Ashcroft, 501 U. S., at 460.
The actual scope of the Federal Government's authority with respect to the States has changed over the years, therefore, but the constitutional structure underlying and limiting that authority has not. In the end, just as a cup may be half empty or half full, it makes no difference whether one views the question at issue in these cases as one of ascertaining the limits of the power delegated to the Federal Government under the affirmative provisions of the Constitution or one of discerning the core of sovereignty retained by the States under the Tenth Amendment. Either way, we must determine whether any of the three challenged provisions of the Low-Level Radioactive Waste Policy Amendments Act of 1985 oversteps the boundary between federal and state authority.
B
Petitioners do not contend that Congress lacks the power to regulate the disposal of low level radioactive waste. Space in radioactive waste disposal sites is frequently sold by residents of one State to residents of another. Regulation of the resulting interstate market in waste disposal is therefore well within Congress' authority under the Commerce Clause. Cf. Philadelphia v. New Jersey, 437 U. S. 617, 621-623 (1978); Fort Gratiot Sanitary Landfill, Inc. v. Michigan Dept. of Natural Resources, 504 U. S. 353, 359 (1992). Petitioners likewise do not dispute that under the Supremacy Clause Congress could, if it wished, pre-empt state radioactive waste regulation. Petitioners contend only that the Tenth Amendment limits the power of Congress to regulate in the way it has chosen. Rather than addressing the problem of waste disposal by directly regulating the generators and disposers of waste, petitioners argue, Congress has impermissibly directed the States to regulate in this field.
Most of our recent cases interpreting the Tenth Amendment have concerned the authority of Congress to subject state governments to generally applicable laws. The Court's jurisprudence in this area has traveled an unsteady path. See Maryland v. Wirtz, 392 U. S. 183 (1968) (state schools and hospitals are subject to Fair Labor Standards Act); National League of Cities v. Usery, 426 U. S. 833 (1976) (overruling Wirtz) (state employers are not subject to Fair Labor Standards Act); Garcia v. San Antonio Metropolitan Transit Authority, 469 U. S. 528 (1985) (overruling National League of Cities) (state employers are once again subject to Fair Labor Standards Act). See also New York v. United States, 326 U. S. 572 (1946); Fry v. United States, 421 U. S. 542 (1975); Transportation Union v. Long Island R. Co., 455 U. S. 678 (1982); EEOC v. Wyoming, 460 U. S. 226 (1983); South Carolina v. Baker, 485 U. S. 505 (1988); Gregory v. Ashcroft, supra. This litigation presents no occasion to apply or revisit the holdings of any of these cases, as this is not a case in which Congress has subjected a State to the same legislation applicable to private parties. Cf. FERC v. Mississippi, 456 U. S. 742, 758-759 (1982). This litigation instead concerns the circumstances under which Congress may use the States as implements of regulation; that is, whether Congress may direct or otherwise motivate the States to regulate in a particular field or a particular way. Our cases have established a few principles that guide our resolution of the issue.
1
As an initial matter, Congress may not simply "commandee[r] the legislative processes of the States by directly compelling them to enact and enforce a federal regulatory program." Hodel v. Virginia Surface Mining & Reclamation Assn., Inc., 452 U. S. 264, 288 (1981). In Hodel, the Court upheld the Surface Mining Control and Reclamation Act of 1977 precisely because it did not "commandeer" the States into regulating mining. The Court found that "the States are not compelled to enforce the steep-slope standards, to expend any state funds, or to participate in the federal regulatory program in any manner whatsoever. If a State does not wish to submit a proposed permanent program that complies with the Act and implementing regulations, the full regulatory burden will be borne by the Federal Government." Ibid.
The Court reached the same conclusion the following year in FERC v. Mississippi, supra. At issue in FERC was the Public Utility Regulatory Policies Act of 1978, a federal statute encouraging the States in various ways to develop programs to combat the Nation's energy crisis. We observed that "this Court never has sanctioned explicitly a federal command to the States to promulgate and enforce laws and regulations." Id., at 761-762. As in Hodel, the Court upheld the statute at issue because it did not view the statute as such a command. The Court emphasized: "Titles I and III of [the Public Utility Regulatory Policies Act of 1978 (PURPA)] require only consideration of federal standards. And if a State has no utilities commission, or simply stops regulating in the field, it need not even entertain the federal proposals." 456 U. S., at 764 (emphasis in original). Because "[t]here [wa]s nothing in PURPA 'directly compelling' the States to enact a legislative program," the statute was not inconsistent with the Constitution's division of authority between the Federal Government and the States. Id., at 765 (quoting Hodel v. Virginia Surface Mining & Reclamation Assn., Inc., supra, at 288). See also South Carolina v. Baker, supra, at 513 (noting "the possibility that the Tenth Amendment might set some limits on Congress' power to compel States to regulate on behalf of federal interests"); Garcia v. San Antonio Metropolitan Transit Authority, supra, at 556 (same).
These statements in FERC and Hodel were not innovations. While Congress has substantial powers to govern the Nation directly, including in areas of intimate concern to the States, the Constitution has never been understood to confer upon Congress the ability to require the States to govern according to Congress' instructions. See Coyle v. Smith, 221 U. S. 559, 565 (1911). The Court has been explicit about this distinction. "Both the States and the United States existed before the Constitution. The people, through that instrument, established a more perfect union by substituting a national government, acting, with ample power, directly upon the citizens, instead of the Confederate government, which acted with powers, greatly restricted, only upon the States." Lane County v. Oregon, 7 Wall., at 76 (emphasis added). The Court has made the same point with more rhetorical flourish, although perhaps with less precision, on a number of occasions. In Chief Justice Chase's much-quoted words, "the preservation of the States, and the maintenance of their governments, are as much within the design and care of the Constitution as the preservation of the Union and the maintenance of the National government. The Constitution, in all its provisions, looks to an indestructible Union, composed of indestructible States." Texas v. White, 7 Wall. 700, 725 (1869). See also Metcalf & Eddy v. Mitchell, 269 u. S. 514, 523 (1926) ("[N]either government may destroy the other nor curtail in any substantial manner the exercise of its powers"); Tafflin v. Levitt, 493 U. S. 455, 458 (1990) ("[U]nder our federal system, the States possess sovereignty concurrent with that of the Federal Government"); Gregory v. Ashcroft, 501 U. S., at 461 ("[T]he States retain substantial sovereign powers under our constitutional scheme, powers with which Congress does not readily interfere").
Indeed, the question whether the Constitution should permit Congress to employ state governments as regulatory agencies was a topic of lively debate among the Framers. Under the Articles of Confederation, Congress lacked the authority in most respects to govern the people directly. In practice, Congress "could not directly tax or legislate upon individuals; it had no explicit 'legislative' or 'governmental' power to make binding 'law' enforceable as such." Amar, Of Sovereignty and Federalism, 96 Yale L. J. 1425, 1447 (1987).
The inadequacy of this governmental structure was responsible in part for the Constitutional Convention. Alexander Hamilton observed: "The great and radical vice in the construction of the existing Confederation is in the principle of LEGISLATION for STATES or GOVERNMENTS, in their CORPORATE or COLLECTIVE CAPACITIES, and as contradistinguished from the INDIVIDUALS of whom they consist." The Federalist No. 15, p. 108 (C. Rossiter ed. 1961). As Hamilton saw it, "we must resolve to incorporate into our plan those ingredients which may be considered as forming the characteristic difference between a league and a government; we must extend the authority of the Union to the persons of the citizens-the only proper objects of government." Id., at 109. The new National Government "must carry its agency to the persons of the citizens. It must stand in need of no intermediate legislations…. The government of the Union, like that of each State, must be able to address itself immediately to the hopes and fears of individuals." Id., No. 16, at 116. The Convention generated a great number of proposals for the structure of the new Government, but two quickly took center stage. Under the Virginia Plan, as first introduced by Edmund Randolph, Congress would exercise legislative authority directly upon individuals, without employing the States as intermediaries. 1 Records of the Federal Convention of 1787, p. 21 (M. Farrand ed. 1911). Under the New Jersey Plan, as first introduced by William Paterson, Congress would continue to require the approval of the States before legislating, as it had under the Articles of Confederation. 1 id., at 243-244. These two plans underwent various revisions as the Convention progressed, but they remained the two primary options discussed by the delegates. One frequently expressed objection to the New Jersey Plan was that it might require the Federal Government to coerce the States into implementing legislation. As Randolph explained the distinction, "[t]he true question is whether we shall adhere to the federal plan [i. e., the New Jer
