Editorials: How to Solve the Redistricting Mess | Bloomberg
To adhere to a standard of “one person, one vote,” the Supreme Court requires each congressional district to contain a roughly equal number of people. The court has also ruled that gerrymandering legislative maps to dilute the power of racial minorities is unlawful (though its commitment to that view might be questioned). However, the court has avoided taking a stand on partisan gerrymanders, by which legislative maps are manipulated to give a decisive advantage to one party over another. This month, it sent claims on gerrymandered districts in several states back to lower courts. That’s unfortunate. Political gerrymanders, whether by Democrats or Republicans, undermine confidence in the political system, add to an already abundant supply of partisan rancor, and discriminate against the Americans whose votes are discounted.
