President James Madison shaped the course of American history in not one, not two, but three different and foundational roles in the formation of the young republic. He was a drafter of the constitution, a leader of the Democratic-Republican party, and America’s first wartime president. In a sweeping biography, Noah Feldman traces Madison’s distinct roles and their resonance in current politics in his new book “The Three Lives of James Madison: Genius, Partisan, President.” Jack Goldsmith recently interviewed Noah Feldman on the book. Together, they discussed Madison’s dynamic role in shaping America’s Constitution, his influence on national security, including the use of economic sanctions, and much more.
