In Rucho v. Common Cause, the Supreme Court declared that partisan gerrymandering is a nonjusticiable political issue. Two factors seem key to the Court’s holding: the difficulty of finding a manageable standard to assess such claims and the thorny expansion of judicial review into an area of deep political controversy. Some of these same concerns permeate Second Amendment litigation; but, perhaps surprisingly, they gave the Heller majority no pause when it first announced an individual right to keep and bear arms.
