## Introduction

Federalism is one of the core constitutional ideas in AP Government. It explains how the United States divides authority between the national government and the states. This matters because many political conflicts are really arguments over federalism, even when they appear to be about schools, guns, marijuana, health care, immigration, or the environment.

The key exam idea is that federalism is not fixed. The Constitution created a framework, but the actual balance of power has shifted over time. Sometimes the national government has expanded its authority. At other times, the Supreme Court or political pressure has protected state power. To do well on the exam, you need to know both the structure and the changes.

> **Key Term: federalism**
> A constitutional system in which power is divided and shared between the national government and state governments.

### Constitutional foundations of shared power

The Constitution does not give all power to one level of government. Instead, it divides power in several ways. This was meant to avoid two dangers at once: a national government that was too weak, like under the Articles of Confederation, and a national government that could crush state authority.

The national government receives certain listed powers, mainly in **Article I, Section 8**. These are often called delegated or enumerated powers. States keep powers not given to the national government, which is the core idea of the **Tenth Amendment**. Some powers are shared by both.

> **Key Term: delegated powers**
> Powers specifically granted to the national government by the Constitution; also called enumerated powers.
>
> **Key Term: reserved powers**
> Powers kept by the states or the people because they are not delegated to the national government nor denied to the states.
>
> **Key Term: concurrent powers**
> Powers shared by both the national and state governments.

A strong AP answer should show the difference clearly:

- **Delegated powers**: declare war, coin money, regulate interstate commerce, make treaties, establish post offices
- **Reserved powers**: run elections, establish local governments, regulate intrastate business, oversee education, protect public health and safety
- **Concurrent powers**: tax, borrow money, establish courts, make and enforce laws

Students often confuse reserved and concurrent powers. For example, taxation is **not** only a state power. Both levels tax, so it is concurrent. Education, by contrast, is mainly a reserved state power.

The Constitution also includes two clauses that often strengthen national power. The **Necessary and Proper Clause** allows Congress to make laws needed to carry out its enumerated powers. The **Supremacy Clause** says that the Constitution, valid federal laws, and treaties are the supreme law of the land.

> **Key Term: Necessary and Proper Clause**
> The clause in Article I, Section 8 that allows Congress to make laws needed to carry out its enumerated powers; also called the Elastic Clause.
>
> **Key Term: Supremacy Clause**
> The clause in Article VI stating that the Constitution, valid federal laws, and treaties are the supreme law of the land.

These two clauses work together. The Necessary and Proper Clause expands what Congress can do. The Supremacy Clause makes valid federal action prevail over conflicting state action. That does not mean the federal government can do anything it wants. Federal action still has to be constitutional.

Brutus No. 1 warned that these clauses could let the national government swallow the states. Federalist No. 51 defended divided power as a form of protection, arguing that liberty is safer when power is split.

> **Test Tip:** If an FRQ asks you to explain why national power increased, connect your answer to a clause and a case. A clause alone is often not enough for full explanation.

### How Supreme Court cases shifted the balance

Federalism on the AP exam is heavily tied to Supreme Court interpretation. Two required cases are especially important.

In **McCulloch v. Maryland (1819)**, Congress had created a national bank even though the Constitution does not explicitly mention one. Maryland tried to tax the bank. The Supreme Court ruled that Congress could create the bank under the Necessary and Proper Clause and that Maryland could not tax it because federal law is supreme over state law.

This case matters for two reasons. First, it confirmed **implied powers**: Congress can do more than only what is listed word-for-word. Second, it strengthened federal supremacy over the states.

> **Key Term: implied powers**
> Powers not specifically listed in the Constitution but reasonably inferred from enumerated powers, usually through the Necessary and Proper Clause.

The logic matters. If Congress can regulate money and national finance, then creating a bank can be a reasonable means to carry out that power. If a state could tax a federal institution, it could weaken or destroy it. So the Court protected national authority.

By contrast, **United States v. Lopez (1995)** placed a limit on federal power. Congress had passed the Gun-Free School Zones Act, arguing that guns near schools affected interstate commerce. The Court rejected that argument and held that carrying a gun in a school zone was too far removed from interstate commerce.

This case is important because it showed that the **Commerce Clause** is broad, but not unlimited.

> **Key Term: Commerce Clause**
> The constitutional provision giving Congress power to regulate commerce with foreign nations, among the states, and with Native American tribes.

After Lopez, students should not conclude that states always win. A better conclusion is that federalism is dynamic. Some cases expand national power; some protect state autonomy.

You should also know a few strong illustrative examples:

- **Gonzales v. Raich (2005)**: upheld federal power to regulate locally grown medical marijuana because it was part of a broader interstate commerce scheme
- **Printz v. United States (1997)**: ruled the federal government cannot force state officials to carry out federal law
- **South Dakota v. Dole (1987)**: upheld conditional federal spending tied to the drinking age
- **NFIB v. Sebelius (2012)**: said Congress may encourage states with funding, but cannot coerce them by threatening massive existing Medicaid funds

A useful pattern:

- **McCulloch, Raich, Dole** -> stronger national power
- **Lopez, Printz, NFIB** -> stronger state autonomy or limits on national power
  > **Test Tip:** In a Supreme Court comparison FRQ, do not just summarize facts. State the constitutional clause, the ruling, and how the case shifted power toward either the states or the national government.

### Models of federalism and how money shapes policy

Federalism has changed over time. In **dual federalism**, the state and national governments are seen as occupying separate spheres. This is often called **layer cake federalism**. The idea is that each level has its own responsibilities.

> **Key Term: dual federalism**
> A model of federalism in which state and national governments operate in separate, distinct spheres of authority.

Later, the United States moved toward **cooperative federalism**, sometimes called **marble cake federalism**, where responsibilities overlap more. This became more common during and after the New Deal, when the federal government funded programs that states helped administer.

> **Key Term: cooperative federalism**
> A model of federalism in which national, state, and local governments share responsibilities and work in overlapping policy areas.

Today, AP Gov often emphasizes **fiscal federalism**. This means the national government uses money to influence state and local policy.

> **Key Term: fiscal federalism**
> The use of federal funding, usually through grants, to influence state and local policy.

Money matters because the national government does not always command the states directly. Instead, it often shapes state behavior through grants.

There are two main grant types you must distinguish:

- **Categorical grants**: for specific purposes, with clear conditions and less state flexibility
- **Block grants**: for broad areas, with more state discretion
  > **Key Term: categorical grants**
  > Federal grants for a specific purpose, usually with strict conditions attached.
  >
  > **Key Term: block grants**
  > Federal grants given for a broad policy area, allowing states more flexibility in how the money is spent.

A simple comparison:

- Categorical grant = specific purpose + more federal control
- Block grant = broad purpose + more state flexibility

For example, if Congress gives money only for a precise public health program and tells states exactly how to use it, that is categorical. If Congress gives money for general welfare or community development and lets states decide the exact program design, that is closer to a block grant.

Federalism also creates conflict through **mandates**.

> **Key Term: mandates**
> Federal requirements that state or local governments must follow.
>
> **Key Term: unfunded mandates**
> Federal requirements that state or local governments must follow without receiving enough federal money to pay for them.

Mandates often produce tension because states may agree with the goal but object to the cost or the loss of autonomy. This is why federalism debates are often really arguments about who pays and who decides.

A classic example of fiscal federalism is **South Dakota v. Dole (1987)**. Congress told states that if they did not raise the drinking age to **21**, they would lose **5%** of federal highway funds. The Supreme Court upheld this. The key principle is that Congress can attach conditions to federal money if the conditions are related to a federal interest and are not coercive.

That last limit matters. In **NFIB v. Sebelius (2012)**, the Court ruled that threatening states with the loss of all existing Medicaid funds if they refused Medicaid expansion was too coercive.

So the AP-level conclusion is not "Congress can always use money however it wants." The better conclusion is: Congress has broad spending power, but there are constitutional limits when financial pressure becomes coercion.
