Democrats Win U.S. House Majority as Republicans Sweep Oklahoma
Democrats secured a substantial U.S. House majority and flipped a North Carolina Senate seat, while Republicans maintained total control of Oklahoma's statewide offices.
The Democratic Party secured a substantial majority in the U.S. House of Representatives during the November 5, 2026, midterm elections, with projected wins of approximately 259 seats. The party flipped seats in several states, including Texas, Ohio, and Montana, and saw Roy Cooper defeat Republican Michael Whatley by nearly 20 points to flip a U.S. Senate seat in North Carolina. In North Carolina, Democrats also likely secured a supermajority in the state House, though voters still passed Republican-led constitutional amendments regarding Voter ID and tax caps. Voters reportedly penalized the GOP over high prices and the war in Iran.
In contrast, Oklahoma Republicans swept all statewide offices and retained every seat in the state's congressional delegation. Republican Mike Mazzei won the gubernatorial race with 52% of the vote, defeating Democrat Cyndi Munson. Kevin Hern won the state's open Senate seat. Despite these top-line wins, Oklahoma Democrats flipped five Republican seats in the state House of Representatives in metropolitan and suburban areas.
Oklahoma's federal influence is expected to decline following the Democratic sweep of both congressional chambers. Republican lawmakers Tom Cole, James Lankford, and Frank Lucas will lose key committee chairmanships, limiting the state's ability to drive federal spending and agricultural policy. In Oklahoma, voter turnout declined to approximately 45%, a 5-percentage point drop from 2022. Technical issues in Comanche and Cleveland counties delayed reporting, requiring manual counts and backup systems.
