James Kingston leads trader consensus at 65.5% implied probability in the GA-01 Republican primary due to his dominant fundraising—over $1.8 million raised—and name recognition from his father Jack Kingston's two-decade tenure representing the district, positioning him as the establishment frontrunner in this open seat race after incumbent Buddy Carter's Senate bid. Chatham County Commissioner Patrick Farrell follows at 41.2% on local appeal and early MAGA endorsements, while retired Army Lt. Col. Brian Montgomery holds 30.8% leveraging military credentials and grassroots backing from figures like Rep. Glenn Grothman. With early voting underway and debates highlighting contrasts among the six candidates, the May 19 primary remains fluid in this crowded field, where turnout in coastal Georgia counties could tip the balance.
