Akhil Reed Amar, the Sterling Professor of Law and Political Science at Yale University, clarifies distinctions between the Fifteenth Amendment, which focuses specifically on racial dimensions of voting rights, and the Fourteenth Amendment, which grants equality and citizenship to all U.S.-born persons. Amar points out that by guaranteeing fundamental rights and due process to all persons, the Fourteenth Amendment assures that even U.S. residents “who aren’t citizens also have Constitutional rights.”
