Annie Andrews leads trader consensus at 89.5% in the South Carolina Democratic Senate primary due to her commanding early polling margins, superior fundraising—recent FEC filings show her with over $150,000 raised compared to rivals' minimal hauls—and endorsements from progressive groups and local influencers. No major shifts occurred in the past week, but her momentum stems from a mid-September poll giving her 42% support versus Catherine Fleming Bruce's 12% and Kyle Freeman's 8%, with the rest undecided in a fragmented field. The June 2026 primary remains distant, leaving room for challengers if turnout surges among activist bases, though structural advantages like incumbency-free dynamics favor Andrews' visibility in this deep-red state's Democratic contest.
