‘One Person, One Vote’ Case Divides U.S. Supreme Court

A divided U.S. Supreme Court grappled with the meaning of the “one person, one vote” principle, hearing arguments in a case that might transform the way legislative maps are drawn and reduce Hispanic clout in elections.

The court is weighing whether states and local governments can continue their decades-old practice of using total population as the basis for drawing equal-sized voting districts. Two Texas voters say the measure should instead be eligible voters, an approach that would reduce representation for areas with lots of children and non-citizens.
