Gray v. Sanders

Background

A Fulton County voter sued Georgia officials who ran Democratic primaries to stop the state’s county unit system, which gave each county a set number of “unit” votes when choosing nominees for U.S. Senator and other statewide offices. The complaint said the system made some counties’ votes worth far more than others (for example, one small county’s unit vote represented 938 people while one Fulton County unit vote represented 92,721). The District Court found the amended county unit law still had serious disparities and issued an injunction against systems that produced invidious weighting.

Reasoning

The Supreme Court majority agreed the party primary counts were state action and that a qualified voter could sue. The Court rejected analogies to the Electoral College or legislative apportionment and held that, in a statewide election, each voter must have equal weight—“one person, one vote.” It concluded Georgia’s county unit system improperly weighted rural votes more than urban votes and therefore violated the Equal Protection Clause. The Court vacated the lower-court judgment and sent the case back so a decree consistent with the Court’s opinion could be entered.

Real world impact

The decision requires Georgia to count statewide primary votes without the county-unit weighting that gave unequal influence to voters in small counties. It affects how parties and state officials must tabulate and certify statewide primary results and protects qualified voters’ equal weight in those elections. The Court also left open further questions about districting and legislative apportionment, noting those issues are different.

Dissents or concurrances

Justice Stewart (joined by Clark) stressed this ruling applies to statewide contests and reinforces one person, one vote; Justice Harlan dissented, arguing history and practical concerns favored allowing some weighting and urged a fuller trial record before sweeping relief.
