New Brennan Center analysis: “Some of this decade’s congressional maps are models of fairness; others are decidedly not. Both parties engaged in gerrymandering after the 2020 census, but, overall, the bias in this cycle’s maps strongly favors Republicans due primarily to aggressive gerrymandering in GOP strongholds in the South and Midwest. In total, the Brennan Center estimates that this gerrymandering will give Republicans an advantage of around 16 House seats in the 2024 race to control Congress compared to fair maps.”
