Republican-led legislatures in Texas, Florida, Louisiana, Alabama, Tennessee, and North Carolina have implemented new congressional maps that alter the composition of several majority-Black and plurality-Black districts. The redistricting process followed a mid-decade push for new boundaries and recent U.S. Supreme Court rulings regarding the Voting Rights Act.
The new maps in these six states generally redistribute Black populations, which have historically voted for Democratic candidates, into districts with larger white majorities. According to 2024 election data, approximately 78% of Black voters in these states supported Kamala Harris. In the Houston metro area of Texas, the new map has already resulted in shifts to the concentrations of Black residents across five districts.
Republican officials stated that the redistricting efforts are intended to improve their party's prospects in upcoming midterm elections. In Texas, the new boundaries are projected to shift five seats toward the Republican party. Critics and voting rights advocates have noted that these changes frequently divide concentrated Black communities into multiple separate districts.
