Democrats flipped seven Republican-held Senate seats in the November 3, 2026 elections, securing chamber control with a projected 54-44 or 54-46 majority once remaining counts conclude. Several contests finished with final margins under 5 points, including Alaska, Mississippi, Florida’s special election, Iowa, Louisiana, Ohio’s special, and South Carolina. Late vote tabulation in Alaska and Mississippi continues to shape exact spreads, while certified results in Iowa, Ohio, and South Carolina already confirm Democratic pickups in the 4- to 5-point range. These outcomes reflect shifts in competitive battlegrounds where polling averages and fundraising favored Democrats in the final weeks, consistent with the broader midterm pattern of reduced Republican margins in Trump-won states. No further Senate contests remain unresolved beyond these margins.
