The last year has seen an unusual spate of mid-decade redistricting. It was initiated by President Trump in 2025 when he urged the Texas legislature to redraw maps to favor Republicans in hopes of helping the GOP hold the House and the 2026 midterms. 

State legislatures are at the center of these efforts in blue and red states. To offer some perspective, we sat down with Erin Covey, who leads coverage of the U.S. House for the Cook Political Report with Amy Walter, and Helen Brewer, who tracks redistricting legislation and developments for NCSL. 

Covey explained the change to congressional maps in Texas, California, Virginia, and other states and discussed how the Supreme Court decision in a Louisiana case involving the Voting Rights Act could affect numerous districts over the next few elections. 

Brewer offered some perspective on the history of redistricting, including mid-decade redistricting. She also discussed the basis and ramifications of the Supreme Court decision in Louisiana v. Callais.
