**Trader consensus on Polymarket heavily favors Kyle Sweetser at 79% implied probability to win Alabama's Democratic U.S. Senate primary on May 19, reflecting his standout visibility as a construction worker and small business owner positioning himself as a populist challenger to Republican senators amid low expected turnout.** Recent local media profiles over the past week, including WSFA and WHNT interviews of all four main candidates—Sweetser, Dakarai Larriett, Everett Wess, and Mark Wheeler—have highlighted the field, but Sweetser's social media traction, including a viral April announcement video and promotion by national commentator Sarah Longwell, sustains his lead. Larriett's 14% share stems from a May 8 attack ad citing Sweetser's past Republican voting record, yet it has not eroded trader confidence absent public polling. Wheeler at 3% and Lamont Lavender at 0.5% lag due to limited recognition in this name-driven primary for the open seat.
