In this documentary, Justices Sandra Day O'Connor and Stephen G. Breyer and other experts discuss how the principle of one person, one vote emerged from a series of landmark decisions in the 1960s, including Baker v. Carr and Reynolds v. Sims. They examine the political environment that led to the decisions and the Court's application of the 14th Amendment's equal protection clause in deciding reapportionment cases. (26 min)
