ATLANTA (AP) — Republican Clay Fuller will try to close the deal with Georgia voters on Tuesday to succeed Marjorie Taylor Greene in Congress, while Democrat Shawn Harris seeks an upset.

Harris led a first round of voting on March 10 with 37% in the district that stretches across 10 counties from suburban Atlanta to Tennessee. While Fuller came in second in the 17-candidate all-party special election with 35%, the Republican candidates combined won nearly 60% of the vote. The 14th District is rated as the most Republican-leaning district in Georgia by the Cook Political Report.

President Donald Trump in February endorsed Fuller, a district attorney who prosecuted crimes in four counties, to succeed Greene in Georgia’s 14th Congressional District. Greene, once among Trump’s most ardent supporters, resigned in January after falling out with the president.

Fuller has backed Trump to the hilt, finding no issue on which he disagreed with the president when asked in a March 23 debate.

“We need an America First fighter to stand strong for northwest Georgia,” Fuller said March 23. He was a White House fellow in the first Trump administration and is a lieutenant colonel in the Georgia Air National Guard.

Trump reiterated his support for Fuller on Monday night.

“I am asking all Republicans, America First Patriots, and MAGA Warriors, to please GET OUT AND VOTE for a fantastic Candidate, Clay Fuller, who has my Complete and Total Endorsement!” the president wrote on social media.

Harris, a cattle farmer and retired general who lost to Greene in 2024, has contrasted himself with Greene’s bomb-throwing style. He said he’s a “dirt-road Democrat” with common sense, and practical-minded Republicans should vote for him because he will focus on the district’s interest.

“He has sold his soul to Donald Trump,” Harris said of Fuller on March 23. “The reality of it is he cannot fight for you because he cannot go against the president.”

The winner will serve out the remaining months of Greene’s term. A Republican win would bolster the party’s slim majority in the House, where Republicans control 217 seats to Democrats’ 214, with one independent.

But if the winner wants to remain in Congress beyond January, he will have to run again. Republicans seeking a full two-year term are set for a May 19 party primary, and possibly a June 16 party runoff, before advancing to the general election in November. Harris is the only Democrat running, meaning he faces no primary election.

Greene was one of the most well-known members of Congress until she left in January. She remained loyal to Trump after he lost to Democrat Joe Biden in 2020, promoting Trump’s falsehoods about a stolen election. When Trump ran again in 2024, she toured the country with him and spoke at his rallies while wearing a red “Make America Great Again” hat.

But Greene began clashing with Trump last year after he and other Republicans pushed back against her running for U.S. Senate or governor. Greene criticized Trump’s foreign policy and his reluctance to release documents involving the Jeffrey Epstein case. The president eventually had enough, saying he would support a primary challenge against her. Greene announced a week later that she would resign.
