Federalism is the system that divides government power between a national government and state governments. This cheat sheet helps students understand who has authority to make laws, enforce rules, collect taxes, and resolve conflicts. It is useful for studying the U.S. Constitution, Supreme Court cases, civic responsibilities, and debates about government power. Knowing the division of powers helps students explain how government decisions affect everyday life.
Key Facts
- Federalism divides power between the national government and state governments so neither level controls all authority.
- Enumerated powers are powers specifically listed in the Constitution, such as coining money, declaring war, regulating interstate commerce, and maintaining armed forces.
- Reserved powers belong to the states under the Tenth Amendment, including running elections, regulating education, issuing licenses, and creating local governments.
- Concurrent powers are shared by national and state governments, such as taxing, borrowing money, building roads, and creating courts.
- The Supremacy Clause means the Constitution, federal laws, and treaties are the highest law when they are validly made.
- The Necessary and Proper Clause allows Congress to pass laws needed to carry out its enumerated powers.
- Preemption occurs when a valid federal law overrides a conflicting state law.
- Checks on federal and state power include courts, elections, constitutional amendments, separation of powers, and public accountability.
Vocabulary
- Federalism
- A system of government in which power is divided between a national government and state or regional governments.
- Enumerated Powers
- Powers specifically listed in the Constitution as belonging to the national government.
- Reserved Powers
- Powers kept by the states or the people because they are not given to the national government by the Constitution.
- Concurrent Powers
- Powers shared by both the national and state governments.
- Supremacy Clause
- The constitutional rule that valid federal law is higher than state law when the two conflict.
- Preemption
- The process by which federal law takes priority over a conflicting state law.
Common Mistakes to Avoid
- Confusing federalism with separation of powers is wrong because federalism divides power between national and state governments, while separation of powers divides power among legislative, executive, and judicial branches.
- Assuming states can ignore any federal law is wrong because the Supremacy Clause makes valid federal law higher than conflicting state law.
- Calling every national power an implied power is wrong because many national powers are enumerated directly in the Constitution.
- Forgetting concurrent powers is a mistake because some powers, such as taxation and creating courts, can belong to both national and state governments.
- Treating the Tenth Amendment as unlimited state power is wrong because state laws must still follow the U.S. Constitution and valid federal law.
