Republicans gained edge over Democrats in redistricting battle, internal party assessment finds

Following an extensive redistricting battle ahead of the 2026 midterm elections, House Republicans gained approximately 10 additional favorable seats through redrawn electoral maps, according to an internal GOP assessment. The redistricting process, which occurred outside the traditional once-per-decade census cycle, was fueled by both parties engaging in partisan map-drawing and was facilitated by a Supreme Court decision weakening the Voting Rights Act. Democrats now must defend 23 House seats in districts that President Trump won in 2024, up from 13 previously, while Republicans hold only eight seats in districts won by Kamala Harris.
