GOP Senate Majority Faces Uncertainty as Key Races Tighten Ahead of Midterms

The Republican majority in the U.S. Senate faces renewed uncertainty as two highly watched Senate races in Ohio and South Carolina are showing increasingly tight margins days before the midterm elections.

In Ohio, Democratic nominee Sherrod Brown holds a narrow lead over Republican incumbent Jon Husted, with polling from Suffolk University showing Brown at 47% support compared to Husted's 44%. The poll has a margin of error of plus or minus 4.4 percentage points, placing the race within its statistical margin. Approximately 4% of voters remain undecided, and 3% support other candidates. Brown, seeking a political comeback after losing his Senate seat in 2024, is campaigning on his policy experience and addressing public concerns about the cost of living.

Meanwhile, in South Carolina, the race between Republican Sen. Darline Graham and Democratic challenger Annie Andrews is a dead heat, according to polling from the Siena Research Institute in partnership with The New York Times. Both candidates are polling at 48%, with 3% of respondents undecided and less than 1% supporting a third candidate. Senator Graham, appointed to the seat in July, is aiming to secure a full six-year term. She has received the backing of President Donald Trump, running in a state that voted for him by a significant margin in the previous presidential election.

Andrews has focused her campaign on framing Graham as inexperienced and an extension of former Senate allies, while advocating for policy positions such as enshrining abortion access, increased gun ownership requirements, and expanded healthcare access. Graham, on the other hand, has emphasized kitchen-table issues. Her opponent, Andrews, has sought to highlight Graham's inexperience and perceived alignment with established political figures. The outcome of these races could significantly influence the balance of power in the Senate, where Republicans currently hold a slim majority.
