Peter Sagal explores the high ideals of the Declaration of Independence that “all men are created equal,” endowed with “inalienable rights,” that didn’t make it into the Constitution in 1787. The Fourteenth Amendment tries to incorporate the words of the Declaration into the Constitution. The far-reaching changes created by that amendment established new notions of citizenship, equal protection, due process, and personal liberty and today those notions are being used to fight for same sex marriage, voting rights, affirmative action, and immigration reform.
