On Monday morning, the justices announced that they would take up a case out of Wisconsin that could result in a ruling on the constitutionality of partisan gerrymandering. But the Supreme Court has never found a plan unconstitutional because of partisan gerrymandering. And since the court has never struck down a map for partisan gerrymandering, that ruling could move the needle in a way we have never seen before. Let's say for the sake of argument that the Supreme Court does rule that partisan gerrymandering is unconstitutional. But basically any movement away from partisan gerrymandering will accrue to Democrats' benefit.
