Geoffrey L. Duncan (born April 1, 1975) is an American politician, businessman, and public speaker who served as the 12th lieutenant governor of Georgia from 2019 to 2023. A former professional baseball pitcher who played six seasons in the minor leagues before a shoulder injury ended his athletic career, Duncan transitioned into the business world and then into politics, winning election to the Georgia House of Representatives in 2012, where he represented the 26th district until 2017. He was elected lieutenant governor of Georgia in 2018 as a Republican, serving under Governor Brian Kemp. Duncan gained national prominence following the 2020 presidential election for his outspoken criticism of Donald Trump's false claims that the election had been stolen, a stance that placed him at odds with much of his own party. He declined to seek re-election in 2022 and subsequently became a political commentator for CNN. In January 2025, the Georgia Republican Party's executive committee passed a resolution to expel Duncan from the state party, though the measure was largely ceremonial since Georgia does not have partisan voter registration. In August 2025, Duncan announced he was joining the Democratic Party, and in September 2025 he entered the race for governor of Georgia in the 2026 election cycle, positioning himself as a centrist candidate in a state that has become a critical battleground in American politics.

Early Life

Geoffrey L. Duncan was born on April 1, 1975, in Atlanta, Georgia. He grew up in the metropolitan Atlanta area and developed an early interest in baseball, which would become the defining pursuit of his youth and young adulthood. Duncan attended the Georgia Institute of Technology, where he played college baseball for the Georgia Tech Yellow Jackets.

Duncan's baseball abilities earned him a path to professional play. After his time at Georgia Tech, he embarked on a professional baseball career as a pitcher, playing six years in the minor leagues. His minor league career is documented in baseball records, which track his time pitching in affiliated minor league systems. A shoulder injury ultimately ended Duncan's professional baseball career, forcing him to pivot to a new chapter in his life.

In a 2025 profile, Christianity Today explored the connections between Duncan's athletic background and his approach to politics, noting that his baseball career instilled strategic thinking and discipline that he later applied in the halls of power. The transition from professional athletics to business and then to public service became a recurring theme in Duncan's personal narrative throughout his political career.

Education

Duncan attended the Georgia Institute of Technology in Atlanta, where he played baseball for the Georgia Tech Yellow Jackets. Georgia Tech served as both the foundation of his athletic career, providing a pathway to professional baseball, and his academic training ground. His time at the university connected him to the broader Atlanta community and the state of Georgia, ties that would later prove important in his political career.

Career

Business Career

Following the end of his baseball career due to injury, Duncan entered the business world. He became involved in the healthcare technology sector, serving in an executive capacity at WellView Health, a company focused on health management services. His business experience became a central part of his political identity, with Duncan frequently presenting himself as a businessman-turned-public-servant during his campaigns. He settled in Forsyth County, north of Atlanta, which became his political base.

Georgia House of Representatives (2013–2017)

Duncan was elected to the Georgia House of Representatives in 2012, representing the 26th district. He took office on January 14, 2013, succeeding Carl Rogers in the seat. During his tenure in the state House, Duncan served as a Republican legislator focused on business-friendly policies. He served in the Georgia House until August 28, 2017, when he resigned to focus on his campaign for lieutenant governor. He was succeeded in the 26th district seat by Marc Morris.

In April 2017, Duncan announced his candidacy for lieutenant governor of Georgia, positioning himself as a conservative outsider with both business credentials and legislative experience.

Lieutenant Governor of Georgia (2019–2023)

2018 Election

Duncan ran for lieutenant governor in the 2018 Republican primary, casting himself as an outsider candidate and former professional athlete with a background in business. He advanced through a competitive primary field and won the Republican runoff, declaring victory after no recount was requested by his opponent. Duncan went on to win the general election in November 2018, succeeding Casey Cagle as lieutenant governor.

Inauguration and Tenure

Duncan was sworn in as the 12th lieutenant governor of Georgia on January 14, 2019, alongside Governor Brian Kemp. As lieutenant governor, Duncan served as president of the Georgia State Senate, presiding over the chamber and influencing legislative priorities. He worked alongside Kemp's administration on various policy matters during his four-year term.

Response to the 2020 Presidential Election

Duncan emerged as one of the most prominent Republican officials in the country to openly challenge Donald Trump's claims that the 2020 presidential election had been stolen. In the aftermath of the election, as Trump and his allies focused intense pressure on Georgia—a state that Joe Biden narrowly won—Duncan repeatedly spoke out against the false fraud claims and efforts to overturn the results.

In an April 2021 CNN appearance, Duncan addressed the issue of voter fraud claims directly, pushing back against the narrative promoted by Trump and his supporters. He described the Republican Party's alignment with Trump's election denial as a short-term strategy that would ultimately harm the party, predicting that the "short-term sugar high" of loyalty to Trump would not last.

Duncan and Governor Brian Kemp resisted calls from Trump allies to convene a special session of the Georgia legislature to address the election results, a stance that further cemented Duncan's reputation as a Trump critic within the Republican Party. The Associated Press reported on Duncan's break with Trump as part of the broader tensions within the Republican Party over election integrity claims.

Decision Not to Seek Re-election

In 2022, Duncan announced that he would not seek a second term as lieutenant governor. The Atlanta Journal-Constitution reported on his decision, noting that his criticism of Trump had made him a target within the Georgia Republican Party and had complicated any path to re-election within the party's primary electorate. Fellow Republican Burt Jones was subsequently elected to succeed Duncan as lieutenant governor. At the time of his departure, there was speculation about Duncan's future political ambitions, including a potential presidential campaign, though that did not materialize.

Post-Office Career and CNN Commentary

After leaving the lieutenant governor's office in January 2023, Duncan became a political commentator for CNN, where he provided analysis on Republican Party politics and the ongoing influence of Donald Trump within the GOP. His role at CNN gave him a national platform from which to continue articulating his vision of a Republican Party that moved beyond Trump, though events within the party continued to move in the opposite direction.

Party Switch and Gubernatorial Campaign

Expulsion from the Georgia Republican Party

In January 2025, the Georgia Republican Party's executive committee passed a resolution to expel Duncan from the state party and ban him from running as a Republican candidate. However, the resolution was largely ceremonial, as Georgia does not have partisan voter registration, and political parties in the state do not have the legal authority to unilaterally strip partisan affiliation from an individual.

Switch to the Democratic Party

On August 5, 2025, Duncan announced that he was leaving the Republican Party and joining the Democratic Party. WABE reported that Duncan made the announcement while not ruling out a future run for office. The party switch was driven by Duncan's long-standing opposition to Trump's influence over the Republican Party and what he characterized as a fundamental change in the party's direction. In an interview with the Marietta Daily Journal, Duncan described the move as a "heart change," framing his decision in terms that went beyond political strategy.

2026 Georgia Gubernatorial Campaign

In September 2025, Duncan formally entered the race for governor of Georgia as a Democratic candidate. The New York Times reported that Duncan "could prove to be a wild card" in the 2026 election, which the paper described as "a crucial test for Georgia's relatively new status as a" competitive battleground state.

The Associated Press profiled Duncan's candidacy in detail, noting that he "was once a conservative Republican" who, "after recoiling from Donald Trump, became a Democrat." The AP report framed his campaign as a test of whether a former Republican could win a Democratic primary and, if successful, the general election in a closely divided state.

Duncan qualified for the gubernatorial race, with the Forsyth County News noting the filing by a candidate who was a "former Republican lieutenant governor and state representative" running from his Forsyth County base. Early polling in the race was reported by WRDW as candidate qualifying neared its deadline in March 2026.

As part of his campaign, Duncan visited college campuses across the state, including a March 2026 appearance before the Young Democrats of UGA at the University of Georgia in Athens. In interviews, Duncan discussed his policy priorities and positioned himself as a centrist candidate, drawing on his experience in both business and government.

Personal Life

Duncan resides in Forsyth County, Georgia, north of Atlanta. He has three children. Duncan has spoken publicly about his Christian faith, which was explored in a Christianity Today profile that examined the intersection of his athletic background, religious beliefs, and political career.

His party affiliation has shifted over the course of his career. Duncan served as a Republican from the start of his political career through 2025, when he announced he was joining the Democratic Party. In the Marietta Daily Journal interview, Duncan described this transition in personal terms, referring to it as a "heart change" rather than a purely political calculation.

Recognition

Duncan's stance against election denialism following the 2020 presidential election brought him significant national attention. His willingness to criticize Donald Trump's false claims about the election, while serving as a Republican lieutenant governor in a state at the center of the post-election controversy, was covered by major national media outlets including CNN, Fox News, the Associated Press, and the Atlanta Journal-Constitution.

His subsequent party switch and entry into the 2026 gubernatorial race attracted coverage from the New York Times and the Associated Press, both of which framed his candidacy as a notable development in Georgia's evolving political landscape. Christianity Today profiled Duncan in December 2025, examining the role of faith and athletic discipline in his approach to public life.
