The redistricting wars and the Voting Rights Act ruling
A dozen states redrew their congressional maps mid-decade, and the Supreme Court narrowed the Voting Rights Act. Who gains, and why it matters.
What happened
Congressional maps are normally redrawn once a decade after the census. Starting with Texas in August 2025, states began redrawing mid-decade to gain seats for the party in power. Republican-led states that redrew include Texas (+5 Republican seats), Florida (+4), Ohio (+2), Missouri, North Carolina, Tennessee, Louisiana and Alabama (+1 each). California voters approved Proposition 50 (64%–36%) to add about five Democratic-leaning seats, and a court-ordered map in Utah added one. A Virginia referendum for Democrats passed but was struck down by the state's supreme court.
On April 29, 2026, in Louisiana v. Callais, the Supreme Court ruled Louisiana's map an unconstitutional racial gerrymander and sharply limited the Voting Rights Act's requirement to draw majority-minority districts.
The effect
Estimates vary, but the new maps give Republicans a net gain of several seats. Analysts such as Kyle Kondik argue the overall bias is similar to 2018, so the maps alone are unlikely to decide the House. Callais could allow more Southern states to eliminate majority-Black districts before 2028.
Arguments on redrawing
Supporters of the new Republican maps say states have the constitutional power to draw districts and that Democrats gerrymander too, pointing to California and Illinois. Supporters of California's response say it was a necessary counter to Texas and was approved by voters.
Critics on both sides say mid-decade redistricting lets politicians choose their voters, and many favor independent commissions in every state.
Arguments on the Voting Rights Act ruling
Supporters of Callais say drawing districts by race is itself discrimination and that the Constitution should be color-blind. Critics say the ruling will reduce Black representation in the South, where voting is often racially polarized.
