Mississippi: Democrats' gains under the new map broke the Republican supermajority in the Senate.

Mississippi special elections
Democrats gained two Senate seats and one House seat across 10 special elections, eight in the Senate and two in the House. Six of the Senate elections and one of the House elections were the result of redistricting. The state passed new state legislative maps after a three-judge district court panel ruled in July 2024 that the previous maps did not contain enough majority-Black districts.

Democrats’ gains under the new map broke the Republican supermajority in the Senate. Heading into the elections, Republicans held 36 out of 52 Senate seats, one more than the minimum of 35 required to meet the two-thirds threshold. After the elections, Republicans hold 34 seats.
