The U.S. Supreme Court on Tuesday appeared just as divided as it did a year ago over how to rein in excessive partisanship in redistricting, and nowhere was that more clear than in how Justices Neil Gorsuch and Elena Kagan reacted to each others’ comments.

In Rucho v. Common Cause, North Carolina’s Republican-controlled General Assembly intentionally drew district lines to preserve its 10-3 dominance of the state’s congressional delegation even though Republicans captured just 53 percent of the statewide vote in 2016. A three-judge district court said the map was an impermissible partisan gerrymander.
