Republican Clayton Fuller and Democrat Shawn Harris are advancing to a runoff in the special election to serve out the remainder of former Rep. Majorie Taylor Greene’s term in Congress.

Fuller, a local prosecutor and Air National Guard member, is heavily favored in the April 7 runoff in the deep-red northwest Georgia district. He overcame a crowded field of Republican competitors with the help of an endorsement from President Donald Trump in early February.

But his inability to win 50 percent of the vote means the seat will remain open for another month, hampering House Republicans’ already-slim majority.

The election was widely expected to head into a runoff given the high volume of interest in the seat. The crowded special election drew interest from more than 20 candidates after Greene’s abrupt departure from Congress amid her high-profile falling-out with Trump. Greene declined to throw her support behind any candidates in the race, but her legacy and public spat with the president loomed large over the race to replace her in the House.
