lol at the assertion that "it would be easy" but the Constitution does allow Congress to refuse to seat a state's delegation if it engages in eggregious partisan gerrymandering.
How Congress can stop gerrymandering: Deny seats to states that do it.
Chief Justice John Roberts, writing for the court last year in
Rucho v. Common Cause,
acknowledged that drawing districts to assure a party’s advantage was “incompatible with democratic principles,” but he concluded that the practice presented “political questions beyond the reach of the federal courts.”
They’re not beyond the reach of the House of Representatives, though. The most direct path to resolving the perpetual challenge of gerrymandering lies with the House. Quite simply, it can refuse to seat a state delegation achieved through excessive gerrymandering. It has that power. And it can use it to create a process that would prevent hyperpartisanship in setting congressional district lines.
