Georgia's 11th congressional district, covering northern Atlanta exurbs, has shown consistent Republican strength, with the party securing 65.6% in the prior cycle. The open seat after Barry Loudermilk's retirement led to a May 2026 Republican primary and June runoff, where neurosurgeon John Cowan defeated Rob Adkerson by roughly 30 points to claim the nomination. Democrat Chris Harden advanced from the opposing primary. With the general election set for November 3 and a potential runoff on December 1 if no candidate reaches a majority, traders assign 62.3% odds to an outright winner. This reflects the district's partisan lean and Cowan's unified party backing, though midterm turnout dynamics or national shifts could influence the final margin. No major candidate or polling developments have emerged since the June runoff.
