John Cowan leads the GA-11 Republican primary runoff market as the top vote-getter in the May 19 primary with 42.6 percent, advancing against Rob Adkerson who received 21.7 percent and Tricia Pridemore at 19 percent. The June 16 runoff follows retiring Rep. Barry Loudermilk’s endorsement of his former chief of staff Adkerson, while Cowan, a neurosurgeon, benefits from stronger primary support across the district’s Cobb, Cherokee, and surrounding counties. Recent debate exchanges between the two finalists have highlighted differences on economic policy and party alignment, with trader consensus reflecting Cowan’s initial margin and limited movement since the first-round results. No major endorsements or shifts have altered the positioning ahead of the runoff.
