The Oldest Constitutional Question

August 07, 2025

In this episode, Richard Primus of the University of Michigan Law School and John Harrison of the University of Virginia School of Law join to discuss Primus’s new book The Oldest Constitutional Question: Enumeration and Federal Power, which challenges the prevailing understanding of congressional power and argues that Congress is not limited to its textually enumerated powers. Their conversation traces how this fundamental disagreement has shaped key moments in American constitutional history, from the Founding Era to the New Deal, and why the debate remains unsettled today.
