John Cowan, a neurosurgeon from Cartersville, won the Republican runoff on June 16, 2026, securing the nomination for Georgia's 11th Congressional District. The Associated Press called the race shortly after polls closed at 7:00 PM ET, according to AP. Cowan beat Rob Adkerson, the former chief of staff to outgoing six-term incumbent Barry Loudermilk.
The win sets up a November general election matchup against Democrat Chris Harden, an estate planning attorney from Woodstock. The district leans heavily Republican, with a Cook Partisan Voting Index of R+12. In 2024, Donald Trump carried it with 61% of the vote, per Yahoo News.
Loudermilk's Retirement Opened a Rare Competitive Primary
The race began in February 2026 when Barry Loudermilk surprised the district by announcing he would not seek re-election after 11 years. His retirement opened one of Georgia's most reliably Republican seats, drawing eight candidates into the GOP primary, according to 10TV. Loudermilk chaired the House Administration Committee's Elections Subcommittee and chose not to endorse a successor.
On May 19, no candidate crossed the required 50% threshold. Cowan led the field with 38.2%, collecting 10,327 votes. Adkerson finished second with 25.0%, or 6,765 votes, forcing the runoff, per KDH News. John Hobbs placed third with 6.86% and Lisa Carlquist fourth with 4.52%.
Cowan Ran as a Problem-Solver, Not a Firebrand
Cowan built his campaign around a message of expertise over politics. He founded Cortex Toys and described himself as a "Conservative Outsider." He campaigned on healthcare costs and cutting federal red tape. "I'm not running to be loud or to chase headlines," Cowan said in a campaign statement. "I'm running to put people ahead of politics."
Cowan previously ran for Congress in 2020 in Georgia's 14th District, losing a runoff to Marjorie Taylor Greene. This time, he entered the race with $1.5 million in early funds, per SM Daily Journal. Total spending across all GOP candidates exceeded $3.66 million before the primary.
Insider vs. Outsider Battle Defined the Runoff
The runoff was framed as a clash between an insider and a professional outsider. Adkerson, as Loudermilk's longtime chief of staff, positioned himself as the most prepared candidate to continue his former boss's legacy. Analysts described him as the "establishment" choice, according to 10TV.
Cowan's victory is seen as a signal that suburban Atlanta voters prefer a more traditional, policy-focused brand of conservatism. Analysts from the Cook Political Report rated the seat "Solid R" throughout the primary. The Republican nominee is considered the "overwhelming favorite" heading into November, per Yahoo News.
General Election Awaits, but District Math Favors Republicans
Cowan will face Democrat Chris Harden on November 3, 2026. Harden won his primary on May 19 with 75% of the vote. He has signaled plans to "flip the seat" by riding suburban momentum. The 11th District covers East and North Cobb, Cherokee, Bartow, Gordon, and Pickens counties — a mix of growing suburbs and rural exurbs, per KDH News.
The math is steep for Democrats. Loudermilk won re-election in 2024 with 65.6% of the vote. The district has not sent a Democrat to Congress in over a decade. Cowan's legislative focus is expected to align with standard Republican platforms, keeping the seat's deep-red status intact, according to SM Daily Journal.
