In a decision having vast significance, the U.S. Supreme Court ruled in 1964 that States must draw their districts to comply with a rule of "one man, one vote" (or "one person, one vote"). This means that districts must be drawn such that the population size of each district is nearly equal. This is called "one man, one vote" because it requires that the relative weight of each man's vote is the same no matter where he lives in the State. His vote cannot be crowded out by living in a district drawn to have a bigger population than other districts in the State. | In a decision having vast significance, the U.S. Supreme Court ruled in 1964 that States must draw their districts to comply with a rule of "one man, one vote" (or "one person, one vote").
