Cowan wins Republican primary for Barry Loudermilk's US House seat in Georgia

WABE · June 17, 2026

John Cowan has won the runoff for the Republican nomination in the race for Georgia’s 11th Congressional District.

Cowan beat Rob Adkerson by 30 percentage points on Tuesday. The winner will go on to the election in November to replace retiring Republican U.S. Rep. Barry Loudermilk. If Cowan wins, it’ll be his first time serving in elected office.

It’s the end of a primary that heavily centered on President Donald Trump’s policies and his favor, despite the president never endorsing anyone in the race.

Loudermilk has held the Republican stronghold district for over a decade. It includes parts of Cobb, Cherokee, Bartow and Pickens counties. He won the seat by 33 percentage points in 2024.

Cowan is a Northwest Georgia neurosurgeon. He finished 21 points higher than Adkerson in the May primary, but finished behind 50% of the vote, forcing a runoff. He previously ran unsuccessfully against former U.S. Rep. Marjorie Taylor Greene in the District 14 Republican primary in 2020.
