Which case held that Congress can regulate intrastate activities that substantially affect interstate commerce, including home-grown marijuana?

• A. Buckley v. Valeo (1976)
• B. Reynolds v. Sims (1964)
• C. Shelby County v. Holder (2013)
• D. Gonzales v. Raich (2005)

Answer: (D)

The question tests Congress’s power under the Commerce Clause to regulate intrastate activity that has a substantial effect on interstate commerce. The key idea is that even actions that happen entirely within one state can be regulated if their combined impact on the national market is significant enough to affect interstate commerce. Gonzales v. Raich (2005) is the case that applies this principle to home-grown marijuana. The Court held that federal regulation of marijuana under the Controlled Substances Act is constitutional, because local cultivation and use, taken together across the country, could substantially affect the nationwide market for controlled substances. Allowing individuals to grow marijuana for personal medical use could undermine the regulatory framework and thus interfere with interstate commerce, so Congress can regulate it. To see why the other cases aren’t the right fit: Buckley v. Valeo concerns campaign finance restrictions and the First Amendment; Reynolds v. Sims deals with equal voting representation; Shelby County v. Holder concerns preclearance under the Voting Rights Act. None of these addresses Congress’s power to regulate intrastate economic activity based on its effects on interstate commerce.
