Potential Democratic Opportunity in South Carolina

Democrat Annie Andrews is closely trailing Republican Senator Darline Graham by only one point in a recent poll. This tight race, highlighted in a poll released Friday, reflects growing interest from Democrats in the traditionally conservative South Carolina as a possibility for gains in the 2026 midterm elections.

Historical Context and Current Dynamics

South Carolina has consistently supported conservatives, backing Donald Trump by almost 18 points in the 2024 presidential election. However, with Trump’s national approval declining, Democrats are aiming to widen their Senate chances in the upcoming November election. Other primarily Republican states such as Kansas and Mississippi, along with key battlegrounds like Alaska and Ohio, are also in their sights.

Polls Indicate a Close Competition

Graham, who assumed her Senate position after the passing of her brother, Lindsey Graham, secured her nomination with Trump’s endorsement. The latest InsiderAdvantage poll shows Graham with 46% support, slightly leading Andrews, who has 45%. Conducted among 1,200 likely voters, the poll includes a margin of error of 2.83 percentage points. Other candidates garnered 5%, while 4% remain undecided.

This recent poll is one of several indicating a competitive race in South Carolina. Previous predictions have misled Democrats, as seen in 2020 when Lindsey Graham ultimately defeated Jaime Harrison despite polls suggesting a tight race.

Current Polling Landscape

Besides the InsiderAdvantage poll, other surveys show Graham ahead by small margins. A Trafalgar Group poll placed her just one point ahead, with a margin of error of 2.9 percentage points. Similarly, a September poll by InsiderAdvantage gave Graham a two-point lead.

These findings reflect a shift from the 2024 election when Trump won decisively with 58% of South Carolina’s votes. Nationally, Democrats show increasing strength. A YouGov and The Economist survey indicates a 15-point Democratic advantage on a general ballot among likely voters.

Comparing Andrews’ and Harrison’s Campaigns

In 2020, Jaime Harrison’s challenge against Graham seemed promising, yet resulted in a clear Republican victory. Polling errors are unpredictable, and it’s uncertain which party might benefit in this cycle. Prior to the 2020 election, a Data for Progress poll showed Graham up by three points, highlighting potential inaccuracies.

South Carolina’s Political Climate

Despite promising poll results, South Carolina remains a difficult environment for Democrats. The state last supported a Democratic presidential candidate in 1976 and has handed Republicans a series of decisive wins in recent cycles.

While the state last elected a Democratic senator in 1998, it provides a promising Democratic base among Black voters, alongside more Democrat-friendly urban areas like Charleston and Columbia. Nevertheless, rural areas and racial polarization have historically given Republicans an edge.

Amid Trump’s declining approval, Democrats sense an opening to compete in conservative states.

Looking Forward

Political forecasters currently favor Graham, labeling her a Likely Republican win by the Cook Political Report and Safe Republican by Sabato’s Crystal Ball. Ongoing polls will be closely monitored, offering insights into voter sentiment ahead of the midterms.
