Campaign themes

These were the policy positions listed on Duncan's website.
| “ |
Ignite a powerful economy by empowering job creators instead of politicians A serial entrepreneur, Geoff previously took a business from his living room to a full-scale operation in a 10,000 square foot facility. He knows what it takes to run a business and meet a payroll, and he knows that bigger government is not the answer. End the bureaucratic stranglehold on education by empowering parents As a father to three boys in the public education system, Geoff has first hand experience of both federal and state government overreach in the classroom. We need to empower parents and not education bureaucrats. True school choice should start at home around the kitchen table. Fight for every innocent life as if it was your own American families are the core of what makes our nation and state great. The unborn need a champion to defend their rights in the face of malicious organizations such as Planned Parenthood. Geoff Duncan is a father and leader who will fight for the next generation. Dismantle ineffective government programs and streamline budgeting process Georgia needs business friendly leadership focused on growing businesses in our state and not the government’s bloated budget. Geoff would have churches, charities, corporations, and citizens as the front line of defense against challenges in our state, not another government program.[16] |

Scorecards
A scorecard evaluates a legislator’s voting record. Its purpose is to inform voters about the legislator’s political positions. Because scorecards have varying purposes and methodologies, each report should be considered on its own merits. For example, an advocacy group’s scorecard may assess a legislator’s voting record on one issue while a state newspaper’s scorecard may evaluate the voting record in its entirety.
Ballotpedia is in the process of developing an encyclopedic list of published scorecards. Some states have a limited number of available scorecards or scorecards produced only by select groups. It is Ballotpedia’s goal to incorporate all available scorecards regardless of ideology or number.

Noteworthy events
Geoff Duncan expelled from state party
On January 6, 2025, the Republican Party of Georgia voted unanimously to expel former Lieutenant Governor of Georgia Geoff Duncan from any further participation or future association with the state party. Explaining its decision, the party levied several accusations against Duncan, including allegedly undermining Republican candidates and endorsing Democrats.[18]
Of the expulsion, Duncan said, “There’s been a growing divide amongst many Republicans in Georgia when the party started focusing 110 percent of their efforts on trying to defend a rigged 2020 election — in their words, not mine — and committing 100 percent of their financial resources, or a majority of their financial resources, to defending folks that were indicted for felony counts,” and “...quite honestly, badges of honor come in all kinds of shapes and sizes, and this is one of those where I don’t want to be associated with a group that thinks that the best direction forward is chaos and confusion.”[19]
On March 18, 2020, Duncan announced a self-quarantine after a member of the Georgia State Senate tested positive for coronavirus.[20]
