Nearly sixty years ago in Reynolds v. Sims,1 the Supreme Court held that the Equal Protection Clause requires state and local legislative districts to be apportioned on a population basis. In other words, districts must contain equal populations. The Court has grounded this rule in advancing both voter equality and representational equality. Representational equality—the notion that each elected official should represent the same number of people—easily follows from Reynolds. However, voter equality—the idea that each district should have the same number of voters—seems to be in tension with this principle. Two districts with the same number of people may have different numbers of voters. Yet Reynolds raises voter equality as a rationale for its population apportionment rule. These seemingly contradictory justifications raise the question as to whether states may apportion their legislative districts according to a metric other than total population in order to achieve voter equality at the expense of representational equality. Such other metrics may include voter eligible population or the number of registered voters in a jurisdiction. This Contribution argues that the tension between voter equality and representational equality that pervades one person, one vote jurisprudence is already accommodated on the state and local level through the Court’s departure from requiring exact mathematic equality among those district populations.
