“Yet what happened this spring in Oregon is just one example, though perhaps the most extreme one, of a larger trend vexing Democratic strategists and lawmakers focused on maximizing the party’s gains in redistricting. In key states over the past decade, Democrats have gained control of state legislatures and governorships that have long been in charge of drawing new maps — only to cede that authority, often to independent commissions tasked with drawing political boundaries free of partisan interference.
Supporters of these initiatives say it’s good governance to bar politicians from drawing districts for themselves and their party. But exasperated Democrats counter that it has left them hamstrung in the battle to hold the House, by diluting or negating their ability to gerrymander in the way Republicans plan to do in many red states. And with the House so closely divided, Democrats will need every last advantage to cling to their majority in 2022.”
