Nine states use new congressional maps for midterms
Approximately 10% of U.S. voters face redistricted boundaries this cycle, with Republicans projected to gain the most seats.

Nine states will use newly drawn congressional maps to select their representatives in the November 3 midterms. The Associated Press reports that about one in ten potential U.S. voters now reside in a different district than in 2024. This shift affects millions of ballots as the nation prepares for the election.
The AP analysis suggests the new boundaries favor Republicans more heavily than Democrats. Republicans could gain up to nine additional House seats under these maps. Democrats stand to gain up to six seats. The changes occurred outside the standard ten-year post-census schedule, driven by political maneuvers to secure House control.
Texas accounts for the largest share of affected voters, with more than 6.9 million potential residents in redrawn districts. California follows with over 6.3 million, and Florida with more than 4.5 million. In Utah, a state court decision resulted in new districts for roughly 69% of the state's potential voters.
The redistricting wave began in 2025 after President Donald Trump urged Republicans to redraw lines to maintain House control. During a CNBC interview in August 2025, Trump cited his 2024 presidential victory margin in Texas to justify the changes. He stated, “We have a right to five more seats.”
California responded by approving new districts that could give Democrats up to five extra House seats. Florida Governor Ron DeSantis signed a map designed to help Republicans win four additional seats. Most of the new maps favor Republicans, with California and Utah being the notable exceptions that may benefit Democrats.
Alabama, Louisiana, and Tennessee also modified their districts following an April Supreme Court ruling. The decision weakened federal Voting Rights Act protections for districts with large minority populations. This legal shift allowed these states to adjust boundaries without the previous federal constraints.
Gerrymandering involves manipulating district lines to advantage a specific party. Parties often achieve this by packing opposing voters into few districts or spreading them across many to dilute their influence. A party controlling the legislature or governor's office can typically draw these maps without veto interference.
