Gray v. Sanders Struck Down County Unit System
In the case of Gray v. Sanders involving use of the county unit system to determine election results in the Georgia Democratic Primary, the U.S. Supreme Court ruled that in Georgia the Democratic Primary was essentially a state election. It further struck use of the county unit system and established the famous “one person, one vote” standard for election districts - which meant that no person’s vote in one district can count more than any other person’s vote in any similar other district.
