2026 race

John Cowan, a neurosurgeon who was a candidate for Georgia's 14th district in 2020, is the Republican nominee for Georgia's 11th congressional district, which is based in the northern exurbs of Atlanta.

The seat is open because the Republican incumbent, Barry Loudermilk, who was reelected with 65.63% of the vote in 2024, declined to run again.

In the May 19, 2026, Republican primary Cowan led a seven-candidate field with 42.6%, then defeated Rob Adkerson, Loudermilk's chief of staff, in the June 16 runoff with 65.0% of the vote. Cowan faces Democrat Chris Harden, an attorney, in the general election on November 3, 2026.
