Democrats achieved a historic Senate majority on November 3, 2026, flipping multiple Republican-held seats in states including Texas, South Carolina, Kansas, Iowa, Ohio, Maine, and North Carolina amid voter dissatisfaction with economic conditions and foreign policy. Pre-election polling averages showed several battlegrounds within narrow margins, particularly Iowa, South Carolina, Alaska, and Nebraska, where final tallies hovered near or below 3 points in multiple projections. Vote counting continues in Alaska and Mississippi, where one contest remains within a few thousand ballots, while certified results in other states confirm several outcomes decided by low-single-digit percentages. These patterns reflect the impact of turnout in competitive districts and late shifts in key voting blocs on the final distribution of close races.
