Gray v. Sanders
The Supreme Court struck down Georgia's county unit system for tallying votes in statewide Democratic primaries, ruling that once voters are chosen for a statewide office, every ballot must count equally regardless of which county the voter lives in.
The decision announced the principle of 'one person, one vote' for statewide elections, rejecting Georgia's argument that its system was comparable to the Electoral College, and set the stage for the Court's broader one-person-one-vote rulings on legislative redistricting later that year.
How it got here: A three-judge federal district court found the county unit system unconstitutional as applied but allowed a modified version of it; Georgia officials appealed directly to the Supreme Court.
The Case in Depth
What happened
A Fulton County, Georgia voter sued state Democratic Party officials to stop them from using the state's "county unit system" to tally votes in primaries for U.S. Senator and other statewide offices. Under that system, each county was assigned a set number of "unit votes," so a vote cast in a small rural county could count many times more than a vote cast in a populous county like Fulton, where the voter lived.
The question before the Court
Could Georgia use a county-based "unit vote" system to count ballots in a statewide primary so that a rural voter's ballot counted many times more than an urban voter's?
The Court's answer
No — the Court ruled that Georgia's county unit system, which gave some rural voters up to ten or more times the voting power of urban voters in statewide primaries, violated the Equal Protection Clause. Once a state defines a single statewide constituency and lets everyone in it vote, each person's ballot must count the same, regardless of what county they live in.
The Court rejected Georgia's comparison to the Electoral College and to congressional apportionment, explaining those systems were specific constitutional compromises that don't justify a similar scheme for a state's own elections. It coined the phrase "one person, one vote" to describe the only workable rule for statewide races, while explicitly leaving questions about legislative district-drawing for another day.

Why it matters
Georgia voters in cities like Atlanta had their ballots counted at a small fraction of the weight given to voters in the state's least populous counties in primaries for U.S. Senator, Governor, and other statewide offices. The ruling forced Georgia to count votes equally statewide and gave a strong signal that other states with similarly skewed systems would also have to change.
What changes now
The case returns to the three-judge district court so it can enter a new order consistent with the Supreme Court's ruling, replacing the county unit system with straightforward popular-vote counting for statewide primaries. The decision is a final ruling on the merits of the constitutional question, though the precise remedial decree was left to the lower court. The 'one person, one vote' language previewed the Court's redistricting rulings later that same year and term.
What this does not decide
The Court expressly said this case does not decide how the Equal Protection Clause limits a state legislature's power to draw geographic districts for choosing state or federal legislators, and it did not address whether a state's upper legislative chamber could be apportioned without regard to population.
Concurrences and dissents
Concurrence — Justice Stewart
Justice Stewart, joined by Justice Clark, wrote separately to stress that the ruling is narrow: it does not touch the validity of how Georgia draws legislative districts or any equal-protection questions raised by that kind of apportionment. He emphasized that this case involves only statewide elections for offices like U.S. Senator, Governor, and judges, where only a single constitutional rule can apply — one voter, one vote.
Dissent — Justice Harlan
“A violation of the Equal Protection Clause thus cannot be found in the mere circumstance that the Georgia County Unit System results in disproportionate vote weighting.”Harlan's core objection that unequal vote weighting alone does not violate the Constitution.
Justice Harlan argued the majority's 'one person, one vote' rule has no basis in constitutional text or history, pointing to the Electoral College's own numerical inequality and the Court's earlier rejection of a similar claim in MacDougall v. Green. He argued Georgia could rationally give rural counties more weight to balance urban political power, and that any disparities should be judged as a factual matter of degree rather than declared invalid outright. He would have vacated the injunction and sent the case back for a full trial on a developed record.
How the Court got there
The legal reasoning, step by step
- The Court first held that a political party's primary election is 'state action' under the Fourteenth Amendment because Georgia law heavily regulates how the party runs its primaries, so constitutional limits on the State apply to the primary itself.
- The Court then distinguished this case from Baker v. Carr and Gomillion v. Lightfoot, explaining that it did not involve how a state legislature draws geographic voting districts or apportions legislative seats — problems the Court had addressed, or left open, elsewhere. This case was, in the Court's words, 'only a voting case.'
- The Court rejected Georgia's argument that its county unit system was comparable to the Electoral College or to congressional apportionment among states, reasoning that those structures were specifically written into the Constitution as historical compromises and do not imply that a state may adopt a similar weighting scheme for its own statewide elections.
- Applying the Equal Protection Clause of the Fourteenth Amendment, the Court reasoned that once a State defines a single statewide constituency and lets every qualified person vote, each ballot cast within that constituency must be given equal weight, regardless of the voter's race, sex, occupation, income, or home county.
- Tracing this idea of political equality through the Declaration of Independence, the Gettysburg Address, and the Fifteenth, Seventeenth, and Nineteenth Amendments, the Court concluded that the only workable constitutional rule for a statewide election is 'one person, one vote,' and that Georgia's unit system could not be reconciled with that rule.
