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.
