Southern Redistricting Plan Misses GOP Targets in 2026 Midterms
A new legal analysis says the Supreme Court's Callais ruling failed to produce expected Republican gains in four of six states, though long-term voting rights concerns persist.

The Republican redistricting strategy triggered by the Supreme Court's Callais decision did not yield the expected electoral gains in four of the six affected states. Travis Crum, the Treiman Professor of Law at Washington University in St. Louis, reported this outcome in a recent post on the Election Law Blog. He noted that the mid-decade map changes backfired for the party in the November 2026 elections.
In April 2026, the U.S. Supreme Court issued a ruling in Louisiana v. Callais that narrowed the interpretation of Section 2 of the Voting Rights Act. This section of the law prohibits district maps that dilute minority voting power. The decision led six Southern states to redraw their congressional maps, specifically eliminating majority-minority districts.
Crum stated that the effort to capitalize on these new maps failed on a large scale. He identified Louisiana as the only exception among the six states, though he noted that the district in question is proceeding to a run-off election, a common occurrence in that state. The other four states did not see the anticipated shift in representation.
A surge in Black voter turnout played a central role in limiting the immediate impact of the ruling. Crum described this as a Black backlash that blunted the effects of the new maps. He pointed to the potential Democratic victory in the Mississippi Senate race as evidence of this increased participation across the South.
Despite the midterm results, Crum argued that the doctrinal damage to voting rights protections remains. He cautioned against treating the 2026 numbers as a final verdict on the ruling's long-term effects. He stated that whether Southern Black turnout returns to historical norms is currently unknowable.
The next major test for these voting rights protections will occur in the 2028 and 2030 elections. Crum also highlighted that the post-2030 redistricting cycle will operate under a weakened Section 2, creating a different environment for future map drawing efforts.
