Akhil Reed Amar, Yale Law School professor, turns from constitutional history to the amendments he thinks are actually likely to come. He proposes three tests for judging future amendments: they should expand liberty and equality, attract bipartisan support, and build on ideas already tried out in state constitutions. Amar applies these tests to concrete proposals, including allowing naturalized citizens to become president and abolishing the electoral college, treating state laws as laboratories the federal Constitution often ends up copying. The lecture closes by mapping ten structural features shared across all fifty-one American constitutions (the federal one plus fifty states), arguing these recurring features define a distinctly American constitutional model. Part of Amar's Yale course America's Unwritten Constitution, the talk is organized into clear chapters moving from general principles to specific reform debates and ending on this broader comparative framework.
