What is Federalism?
Federalism in the United States is a system of government in which power is divided between the national government and state governments.
The U.S. Constitution grants specific powers to the federal government while reserving others to the states, creating a layered structure of shared authority that shapes how laws are made, enforced, and interpreted.
Why does it matter?
Federalism generates conflict over the balance of power between state and federal governments, and it has become an effective method for states to challenge federal policies they oppose. For example, there were 160 multistate lawsuits against the first Trump administration and 133 against the Biden administration.[1]
Conflicts often arise over policy issues such as ESG investing, the role of the administrative state, and work requirements for public assistance, among many others. Click here for more information on these state and federal government conflicts.
What are the key arguments?
Supporters of federalism argue that it promotes efficiency, innovation, and healthy competition between states. They believe it strengthens democracy by encouraging local decision-making and citizen participation, while also uniting a diverse nation and respecting state sovereignty.
Opponents argue that federalism can be undemocratic by giving smaller states disproportionate power. They claim it leads to inefficiencies, disparities between states, and weakens national unity.
What's the background?
The Articles of Confederation (1781), the first U.S. constitution, created a weak central government unable to tax, regulate interstate commerce, or enforce laws. These shortcomings led to economic instability and prompted the drafting of a new Constitution in 1787.[2]
The new U.S. Constitution established a federal system dividing power between the national government and the states, following debates between Federalists, who supported a stronger central government, and Anti-Federalists, who sought to protect state authority. It granted enumerated powers to the federal government, such as regulating interstate commerce, taxing, and maintaining armed forces, while the Tenth Amendment reserved powers not delegated to the federal government for the states or the people.[3][4]

Federalism by the numbers. This section links to relevant data on federalism, including:
Prior to the ratification of the United States Constitution, the American government operated under the Articles of Confederation from March 1781 to March 1789. The Articles created a national legislature with powers to declare war, negotiate treaties, maintain an army, and coin money. However, it lacked the authority to tax or regulate commerce, and state governments retained most of their sovereignty and independence.[2][3][4]
The U.S. Constitution, which replaced the Articles, established a stronger national government and a federal system that shared power between the national government and the individual states.[3][4] The Constitution grants specific powers to the federal government, such as regulating interstate commerce, taxing, and maintaining armed forces—these are known as enumerated powers. At the same time, the 10th Amendment ensures that powers not given to the federal government are reserved for the states or the people, maintaining state authority over matters not explicitly addressed by the national government.
To address conflicts between state and federal powers, the Constitution includes mechanisms such as the Supremacy Clause in Article VI, which declares federal law to be the "supreme law of the land." This means federal law takes precedence when state laws conflict with it. The Necessary and Proper Clause (Article I, Section 8) further empowers Congress to make laws necessary to carry out its enumerated powers. Together, these provisions establish a balance of power between the federal government and the states, ensuring both play vital roles in governance.
There are several types of federalism, each representing different ways in which power and responsibilities are shared and balanced between the federal government and state governments, often evolving over time in response to changing political, social, and economic circumstances. Here are two of the most important forms of federalism.
Other types of federalism include competitive federalism, horizontal federalism, market-preserving federalism, and picket-fence federalism, among others. Each type offers a different framework for understanding the relationship between federal and state powers, reflecting varied approaches to governance and policy-making.
State governments may pursue legislative, regulatory, or legal actions to challenge obligations placed on them by the national government. The term federal mandate refers to any regulation or court ruling that imposes a binding obligation on a state or local government, including conditions for federal funding or unfunded mandates.[7]

| What is ESG? ESG investing is an asset management approach that considers the environment, social issues, and corporate governance practices. It's a type of stakeholder investing, which argues shareholder returns should not be the only goal. Stakeholder investing contrasts with traditional approaches that exclusively consider financial factors like balance sheets, income statements, and valuations to maximize risk-adjusted returns (also known as shareholder investing). |
This approach argues that state governments should oppose certain federal mandates allowing or requiring ESG considerations, especially as they relate to state investments. It also argues the federal government should move to prevent foreign governments from enforcing ESG rules on U.S. businesses.
Ballotpedia has identified the following three reform approaches opposing federal ESG mandates:
| What are the five pillars of the administrative state? Ballotpedia's five pillars of the administrative state provide a framework for understanding the authority, influence, and actions of administrative agencies, as well as the policies and arguments surrounding them. The five pillars focus on the control of administrative agencies related to the (1) legislative, (2) executive, and (3) judicial branches of government, (4) the public, and (5) other agencies or sub-agencies. |
Ballotpedia groups these into three categories: state oversight of federal regulations, state oversight of local regulations, and federal oversight of state regulations.
Ballotpedia has tracked the following 10 arguments opposing, nine arguments supporting, and six arguments related to the nature of federalism:
1. Argument: The intentions of the Framers related to federalism have been misunderstood
2. Argument: Federalism is not the same as decentralization
3. Argument: Federalism is the middle-ground between disunity and centralization
4. Argument: Federalism is difficult to maintain
If federalism is wrong or unnecessary, then why?
1. Argument: The Framers were wrong to establish a federal system of government

Here are some of the most important court cases related to federalism, as they have had a significant impact on the balance of power between federal and state governments:
These cases illustrate key moments in the development of federalism, where the balance of power between state and federal governments was tested and defined through judicial interpretation.
Ballotpedia covers a wide range of federalism-related court cases, and this taxonomy shows how those cases are organized into categories, subcategories, and doctrines.

States employ a variety of processes to apply for and administer federal grants. The links below provide information about the general processes applied by the 50 states in order to seek and distribute federal funds.
