Federalism is the constitutional system dividing governing authority between a national government and state governments, with each exercising power in their designated spheres. Under this system, states retain significant autonomy while the federal government handles matters affecting interstate commerce, national security, and other enumerated powers.
When state and federal law conflict, the Supremacy Clause (Article VI) establishes federal law as supreme. But the 10th Amendment reserves all powers not delegated to the federal government to the states or the people. This creates ongoing practical tension: states can set their own education standards, criminal laws, and professional licensing rules, while Congress handles interstate commerce, currency, and foreign policy. The COVID-19 pandemic exposed this friction as governors and federal officials clashed over gathering restrictions, mask mandates, and vaccine requirements.
Federalism creates policy variation across states—what's permitted in one state may be restricted in another. Some see this flexibility as a virtue, allowing states to experiment with different policies. Others view it as a weakness, creating inequality between jurisdictions. The Supreme Court referees federal-state disputes, deciding whether Congress stayed within its enumerated powers and whether states violated the Constitution.
Understanding federalism is essential to grasping which level of government makes decisions about your life. It explains why marijuana is legal in some states despite federal prohibition, why education policy varies dramatically across states, and why citizens often face conflicting rules from different jurisdictions.
People often think the federal government has power over everything. In practice, states retain broad authority over education, local policing, marriage law, professional licensing, and criminal justice unless Congress specifically acts within its enumerated powers.
