John Cowan leads trader sentiment in the Georgia 11th Republican primary runoff at 67.5 percent, ahead of Rob Adkerson at 33.5 percent, after securing 42.6 percent of the vote in the May 19 primary compared with Adkerson’s 21.7 percent. The open-seat contest to succeed retiring Representative Barry Loudermilk advanced only these two candidates, with others eliminated. Cowan’s stronger first-round performance among a crowded field of eight Republicans has shaped the current implied probabilities, though the June 16 runoff remains the decisive contest. Adkerson’s role as Loudermilk’s former chief of staff provides establishment ties that could influence turnout and endorsements in the head-to-head matchup. No major developments have occurred since the primary results, leaving the outcome dependent on voter consolidation and campaign momentum over the next three weeks.
