Democrats made sweeping gains across the South in Tuesday's midterm elections, capturing Republican Senate seats in North Carolina, South Carolina and Texas while making advances in state governments. Mississippi's Senate contest remained unresolved. The results strengthened the region's importance in the battle for Congress and offered both parties a new electoral landscape to assess ahead of the 2028 presidential race.
Republican efforts to secure more favorable House districts produced disappointing results for the party. After a Supreme Court decision earlier this year weakened part of the Voting Rights Act, Republican-led Southern states revised congressional boundaries in hopes of protecting themselves against a difficult midterm election. Instead, Democrats were positioned to gain several seats across the region, including in states where Republicans had redrawn maps.
In Tennessee, the new boundaries divided Memphis among three districts, but Democratic state Rep. Justin Pearson was within a few thousand votes of victory. Alabama Rep. Shomari Figures won by nearly 8 points despite a redraw intended to defeat him in a district with a 14-point Trump advantage. Republicans also targeted nine seats in Texas and Florida. By Wednesday night, the Associated Press had called only one of those seats for Republicans.
Higher Black voter participation helped drive the Democratic gains, with turnout surging in Louisiana and Georgia. Participation had already risen sharply in primaries following the court ruling. Ashley Kennedy Shelton of Louisiana's Power Coalition for Equity and Justice previously told NPR that the decision was "personal" for Black voters. Rising household expenses, the war in Iran and concerns about corruption in the Trump administration were also among the issues motivating voters.
South Carolina recorded its highest turnout for a gubernatorial election year, helped partly by increased Black participation, as Democrat Annie Andrews won a Senate seat. In Louisiana, Democrat Jamie Davis lost to Sen.-elect Julia Letlow by less than 2 percentage points, compared with Trump's margin of more than 15 points in 2024. In Mississippi, Democrat Scott Colom led Republican incumbent Cindy Hyde-Smith by fewer than 1,200 votes, with the race still too close to call.
The effects extended throughout state government. Georgia Sen. Jon Ossoff's 18-point victory helped former Atlanta mayor Keisha Lance Bottoms win the governorship. Democrats captured every statewide elected office, took control of the state utility regulator and were on course for a state House majority. In North Carolina, former Gov. Roy Cooper's 20-point win put multiple congressional seats and control of the state House within reach.
Texas Democrats secured a state House majority, while Republicans lost their House supermajorities in Florida and South Carolina. Dozens of additional Democratic pickups were reported across Alabama, Arkansas, Kentucky and Tennessee, showing that the shift reached beyond the region's most competitive states.
The results also carry consequences for 2028. Potential presidential contenders from both parties had campaigned or supported candidates in the region before Election Day. Republicans retained Florida's governorship and Senate seat, but tighter-than-expected contests there, alongside Democratic victories in Texas, give both parties reasons to invest. Texas, Florida, Georgia and North Carolina together account for more than one-third of the 270 electoral votes required to win the presidency.
