If you’ve ever wondered why a state can legalize marijuana while the federal government still classifies it as a Schedule I drug, you’ve stumbled into one of the oldest arguments in American political life: who’s actually in charge here?
Spoiler: it’s complicated.
The Founders’ Framework
When the Constitution was written in 1787, the Founders had one big goal: avoid the mess of monarchy and the chaos of the Articles of Confederation. What they came up with was federalism—a system where power is divided between a national government and state governments. But not equally, and not always clearly.
The idea was to strike a balance. The federal government would handle big-ticket items like national defense, printing money, and foreign relations. States would retain authority over everything else—like education, elections, and criminal law—under the 10th Amendment, which basically says: “If it’s not listed here, the states get it.”
In theory, this meant shared power. In practice, it meant decades of power struggles and jurisdictional squabbles.
The Federal Shift (And Why It’s Not a Bad Thing)
Over time, especially after the Civil War, the Great Depression, and the Civil Rights Movement, more power has shifted to the federal government. Why? Because the states weren’t always doing a great job—especially when it came to civil rights, economic justice, and infrastructure.
When Alabama says, “States’ rights!” what they often meant was, “We want to keep doing segregation.” When states couldn’t manage economic collapse during the Depression, it was the New Deal (federal programs) that stepped in.
This evolution isn’t a betrayal of the Constitution. It’s the system adapting to modern realities. The Founders may have designed the bones, but they weren’t dealing with nuclear weapons, global markets, or interstate broadband policy. Letting the feds take the lead on big, national issues isn’t centralization—it’s common sense.
The National Guard: A Case Study in Shared Control
Want a real-world example of how layered this power-sharing is? Look no further than the National Guard.
The National Guard is technically part of each state’s militia. Governors can activate them for emergencies—natural disasters, civil unrest, wildfires, etc. But here’s the twist: the federal government can also call up those same Guard units and deploy them overseas or under federal command, like in Iraq or Afghanistan.
This dual allegiance creates tension. In 2020, for instance, some governors resisted federal efforts to deploy Guard troops to quell protests. And yet legally, the President has the authority under the Insurrection Act to override them. This is not the norm, however.
So who controls the National Guard? Both. And that’s kind of the whole point of federalism—it’s a Venn diagram, not a flowchart.
The Flashpoints: Where State and Federal Interests Collide
The push-and-pull between state and federal power isn’t just theoretical—it’s shaped the country’s biggest conflicts:
- Slavery: States used “states’ rights” to defend slavery; the Civil War was the ultimate resolution of that dispute.
- Desegregation: In the 1950s and 60s, Southern states defied federal court orders to desegregate schools. It took federal troops and laws like the Civil Rights Act to enforce constitutional rights.
- Interstate Commerce: From workplace safety to environmental regulations, the federal government has used the Commerce Clause as a way to regulate things states couldn’t (or wouldn’t).
- Social Issues: Abortion, marriage equality, marijuana legalization—each of these has seen states test the boundaries of federal authority.
Sometimes the states lead the charge for change. Other times, federal action is needed to guarantee basic rights. The friction is real—but it’s not necessarily a flaw.
Why the Tension Is by Design
It’s tempting to ask: why not just let one level of government be in charge? But that defeats the purpose. The tension between state and federal power is baked into the system, because no single authority can—or should—control everything in a diverse, continent-sized republic.
Federalism allows for experimentation. States can be “laboratories of democracy,” trying out ideas (like legal weed or ranked-choice voting) before they go national. It also creates redundancies—annoying when you’re filing taxes, useful when you’re voting during a pandemic.
And yes, it creates conflict. But conflict between competing powers is still better than unchecked authority by one.
Final Thoughts: Embrace the Gray Area
When people complain that government is confusing or contradictory, they’re not wrong. But that confusion is a feature, not a bug. A balance of powers—between branches and between levels of government—means that no one entity can steamroll the rest. Frankly, we’ve learned a lot of lessons as a country by testing the question of “State vs Federal power”.
So the next time you hear someone yelling about “federal overreach” or “rogue states,” remember: that’s not the system breaking. That’s the system working exactly as it was meant to—grinding, tugging, resisting, and occasionally cooperating to reflect a country that’s never been simple, and was never meant to be.
