The battle for control of the House is getting messier by the day as a flurry of court rulings and legislative maneuvers reshapes the redistricting landscape. This week alone, both parties scored wins and suffered setbacks, making it increasingly difficult to predict which side will have the upper hand in November.
In South Carolina, Republican state senators rejected a proposed GOP map that would have broken up Representative Jim Clyburn's district. That move, which Clyburn himself blamed for driving record early-vote turnout, was a clear win for Democrats. But in Alabama, a federal court blocked the GOP's preferred congressional lines, though Republicans are now urging the Supreme Court to intervene. Justice Clarence Thomas has asked for briefs by Monday, leaving the fate of that map—and potentially a GOP seat—in limbo.
Meanwhile, judges in Florida and Tennessee dismissed efforts to halt Republican-backed maps, giving the GOP a temporary edge. The Florida map could net Republicans up to four seats, while Tennessee's new lines effectively create a 9-0 GOP delegation, eliminating Representative Steve Cohen's majority-Black district. But litigation in both states is far from over, and the final outcome remains uncertain.
On paper, Republicans still hold a structural advantage. They have more than a dozen pickup opportunities across Texas (5), Florida (4), Ohio (2), Missouri (1), North Carolina (1), Louisiana (1), and Tennessee (1). Democrats, by contrast, have only six potential net gains, concentrated in California (5) and Utah (1). A recent loss in Virginia, where the state supreme court tossed out a referendum that would have allowed Democrats to redraw the map, further narrowed their path.
But the math is far from settled. The Cook Political Report estimates the GOP could gain between five and seven seats, yet still predicts Democrats are favored to hold the majority. “We still believe that Democrats are favored to win control of the House due to the poor national environment for the GOP. But they are no longer overwhelming favorites,” wrote Cook House editor Erin Covey.
The midterm environment itself is a wild card. Special elections have consistently shown Democrats overperforming, including flipping a Florida state House district that includes Trump's Mar-a-Lago club and a reliably red state Senate seat in Texas. But the party's success isn't linear—two Democratic-backed judicial candidates lost to Republican-appointed Georgia Supreme Court justices this month, underscoring the challenges in competitive statewide races.
Texas also offered a stark reminder of the GOP's internal dynamics. In the Senate primary runoff, Attorney General Ken Paxton crushed incumbent Senator John Cornyn, winning by roughly 38 points. Cornyn’s vote share was the lowest for a Senate incumbent in half a century. The race had been closely watched as a bellwether for the midterms, and Trump quickly hailed Paxton’s win as a sign of Republican strength.
As the legal battles drag on and the political environment shifts, the only certainty is uncertainty. The redistricting math is still being written—and the final numbers won’t be known until Election Day.
