September 17, 2015 marks 228 years since the end of the convention of delegates assembled in Philadelphia for the purpose of, in James Madison’s original notes, “revising the federal Constitution” (he later changed “Constitution” to “system of Government”). After 39 of the delegates, including George Washington and Madison, signed the document, it went to the states for ratification, which occurred the next year and then came into force in 1789. Today, more than 200 years later, what would James Madison—often called “the Father of the Constitution”—think about contemporary developments in American politics and public policy? That is the question posed by the authors of a new volume of essays from the Brookings Institution Press. In “What Would Madison Do? The Father of the Constitution Meets Modern American Politics,” 10 prominent scholars explore modern governance and policy issues through the lens of Madison’s constitutional framework.
