John Cowan leads the Republican primary runoff market for Georgia's 11th congressional district after topping the May 19 primary with 42.6 percent of the vote, ahead of Rob Adkerson at 21.7 percent and Tricia Pridemore at 19.0 percent. This performance established Cowan as the frontrunner in the June 16 runoff against Adkerson, the former chief of staff to retiring incumbent Barry Loudermilk. Traders appear to favor Cowan's profile as a neurosurgeon and political outsider emphasizing healthcare and economic issues, while Adkerson benefits from establishment connections but trails in the implied probability. Other candidates remain at minimal levels following their primary elimination, with no major late developments reported in the past week altering the contest dynamics ahead of the runoff.
