Description

Texas, California, and Missouri are moving forward with plans for mid-decade redistricting to gain partisan advantage—with other states threatening to follow. They are not hiding the motive: President Trump asked Texas to gain Republicans seats and Governor Newsom is saying he needs to retaliate. Just how much has gerrymandering gained the parties in Congress? And how much is likely to change now? Eric McGhee finds that both parties are increasingly extreme in gerrymandering but that prior mid-decade redistricting gains have been small. Daniel Kolliner finds that Republican control of redistricting has led to large increases in seat share, with Democratic control gains limited to large states.
