John Cowan leads trader consensus in the Georgia 11th congressional district Republican primary runoff at 66.5 percent implied probability, ahead of Rob Adkerson at 26 percent, following the May 19 initial primary where Cowan captured 42.6 percent of the vote compared with Adkerson’s 21.7 percent. The open seat, created by retiring Representative Barry Loudermilk, advanced the top two finishers to the June 16 runoff under Georgia’s election rules. Adkerson’s positioning draws from his role as Loudermilk’s former chief of staff and local establishment ties, while Cowan’s stronger first-round margin and broader name recognition among primary voters have sustained his lead in recent polling and market pricing. A recent Atlanta Press Club debate between the finalists highlighted differences on economic and healthcare priorities ahead of the final contest.
