Before We Start
Federalism as genuinely shared power, not just divided territory
Federalism describes a system where power is constitutionally shared between a national government and subnational (state) governments — both hold genuine, independent authority, rather than one simply delegating limited authority to the other.
💡 The Concurrent Category Is Often the Least Intuitive
It's relatively easy to grasp powers that belong exclusively to one level of government — but concurrent powers, held by BOTH federal and state governments simultaneously, are worth specific attention since they don't fit the simpler "either/or" mental model.
Mnemonic
The three categories, with specific examples
Expressed Powers
Federal government only
Examples: coining money, declaring war. These powers are constitutionally reserved exclusively to the national government.
Reserved Powers
State governments only
Examples: education, marriage laws. These remain within state authority, not granted to or exercised by the federal government.
Concurrent Powers
Both federal and state governments
Examples: taxing, law enforcement. Both levels of government genuinely exercise these powers simultaneously, rather than one holding exclusive authority.
💊 A useful memory anchor for the examples: "Coin and Combat" for expressed (coining money, declaring war — clearly national-scale functions); "Educate and Espouse" for reserved (education, marriage — clearly local/personal-scale functions); "Tax and Track" for concurrent (taxing, law enforcement — functions that make sense at both levels simultaneously).
⚖️ Applying the Framework — Classifying a Specific Power
A dispute arises over whether a specific governmental function — collecting taxes — belongs exclusively to the federal government, exclusively to state governments, or to both simultaneously.
Classify the Power Correctly
Taxing is a specifically named example of a CONCURRENT power — both the federal government and state governments genuinely exercise independent taxing authority simultaneously, rather than one holding exclusive authority over this function. This is exactly why the concurrent category exists as a distinct classification from expressed and reserved.
Contrast With an Expressed or Reserved Power
This differs meaningfully from a power like declaring war (expressed, federal-only) or setting marriage laws (reserved, state-only) — those two categories involve exclusive authority at one level, while taxing genuinely operates at both levels at once. Correctly identifying which category a given power falls into is the core skill this framework requires.
📌 Exam Application
Federalism power questions test correct classification into the three categories:
Category identification: "Is declaring war an expressed, reserved, or concurrent power?" → Expressed (federal government only).
Category identification: "Is setting marriage laws an expressed, reserved, or concurrent power?" → Reserved (state governments only).
Category identification: "Is law enforcement an expressed, reserved, or concurrent power?" → Concurrent (both federal and state governments).
⚠️ The Trap — Assuming Every Power Belongs Exclusively to One Level of Government
Because expressed and reserved powers fit a simpler "either federal OR state" mental model, it's easy to overlook the concurrent category and assume every governmental function must belong exclusively to one level or the other.
The safeguard: Always check whether a power might be concurrent — genuinely exercised by both levels simultaneously — before assuming it must belong exclusively to one level or the other.
