**Incumbent Republican Brian Jack faces Democrat Maura Keller in Georgia’s 3rd congressional district general election on November 3, 2026.** Jack, who won the seat with 66% in 2024, ran unopposed in the May 19 Republican primary, while Keller secured the Democratic nomination after defeating her primary opponent. The district’s strong Republican lean—reflected in its Solid R rating and historical margins—positions Jack to capture a clear majority on the first ballot under Georgia’s election rules, which require over 50% for an outright win or trigger a runoff between the top two vote-getters. No late developments or credible polling have emerged to suggest a competitive contest or significant vote split that would force a November runoff. Trader consensus at 93.5% on an outright winner aligns with the structural and historical factors favoring the incumbent in this low-competition race.
