Recent primary turnout in South Carolina, including record Republican participation exceeding 325,000 in the August special Senate primary and elevated June voting linked to redistricting debates, points to sustained voter engagement heading into the November general election. The race features Democrat Annie Andrews against the Republican nominee selected after Lindsey Graham’s death, with polling averages showing a modest Republican edge that could encourage higher mobilization on both sides in a midterm cycle. Historical SC midterm participation levels around 40-50 percent of registered voters, combined with factors like early voting access, candidate visibility, and national political conditions, keep multiple turnout bands clustered near 1.7-2 million ballots. Developments such as the August 25 Republican runoff outcome, final nominee messaging, or late shifts in enthusiasm among key voting blocs could widen the range.
