MARIETTA, Ga. — Under the fluorescent lights of an American Legion hall near Atlanta, in front of more than a dozen Democratic activists, Geoff Duncan apologized for all the things that he did as a Republican.
He regrets opposing gun control. He's sorry for fighting the expansion of Georgia's Medicaid program. And he's most remorseful about supporting some of the strictest abortion rules in the country.
''Unlike most folks in politics, I'm willing to say I'm sorry for that," Duncan said.
He's doing a lot of apologizing these days because the former Republican is running for governor as a Democrat, trying to win over members of his newly-adopted party in a crowded primary in a critical battleground state. Although some view Duncan as an interloper, he's pitching himself as Democrats' best chance to break their 24-year losing streak for Georgia's highest office.
''You've got to win more than your base,'' Duncan said. ''And so I'm the only one that shows up in this Democratic primary that's building a big enough coalition of Democrats, independents, and this growing batch of disgusted Republicans.''
Duncan was a standard-issue suburban Republican serving as lieutenant governor until the 2020 election, when he rejected President Donald Trump's false claims about fraud. His stand earned him the respect of many Democrats, and he campaigned for Kamala Harris in 2024. Now he's testing whether that can translate into votes in the party's primary.
He's not the only one. Former Republican congressman David Jolly is running for governor in Florida and former Republican lawyer George Conway is running for Congress in New York City, both as Democrats.
Their success or failure could provide lessons for the national party as it debates whether to focus on progressive ideas or court moderates and even conservatives turned off by Trump. Some still question why Harris barnstormed with Liz Cheney, a former Republican congresswoman, rather than focusing on motivating liberal voters during her failed presidential campaign.
