# US 2026 midterms: Battle for Congressional control intensfiy > Live situation record from CLSTR: https://clstr.news/situations/united-states-2026-midterm-elections > Updated: 2026-09-10T04:43:47.000Z. Sources: 37. Developments: 9. As the November 3 midterm elections approach, the battle for control of Congress has intensified. While Republicans currently hold majorities in both chambers, Democrats are considered favorites to flip the House of Representatives majority. In the Senate, 35 seats are up for competition, with Republicans defending 20 seats and Democrats defending 13. Additionally, two special elections will be held in Ohio and Florida following the transition of Republican senators to high-level positions within the Trump administration. Redistricting has emerged as a central battleground. Republican-led efforts in states such as Texas, Alabama, Tennessee, and Louisiana have redrawn maps to favor the GOP, while California passed a referendum to create more Democratic seats to offset these changes. Utah has also created a safe blue seat in Salt Lake City. These mapping outcomes have been influenced by U.S. Supreme Court decisions regarding the Voting Rights Act. The political landscape remains heavily influenced by President Donald Trump. While he serves as a driver of Republican mobilization, some officials express concern that the elections may serve as a referendum on his presidency amid reports of declining approval ratings. Within the Republican Party, there is perceived narrowing space for debate regarding his political instincts. Meanwhile, the Democratic Party is navigating a populist movement involving candidates who often align with the Democratic Socialists of America, advocating for unionization and specific foreign policy stances regarding the conflict in Gaza. ## Claims - The midterm elections will take place on November 3.
