Former Georgia Lt. Governor Geoff Duncan announced he is formally leaving the Republican Party, writing in an op-ed for the Atlanta Journal-Constitution that his political views have shifted. Duncan said there was “no date on a calendar or line in the sand” marking the change, but pointed to his support for increased government spending on social programs, a pathway to citizenship for undocumented immigrants, and stricter gun control measures.

Duncan, a one-term lieutenant governor elected in 2018, had already broken with the party on several fronts. He endorsed Joe Biden and Kamala Harris, spoke at the Democratic National Convention with Harris’s running mate Tim Walz, and was briefly considered as an independent presidential candidate by the centrist group No Labels.

Georgia Republican Party Chairman Josh McKoon had previously asked Duncan to stop identifying as a Republican, and the party later formally expelled him. In January, Duncan responded, “What took them so long?”

Duncan’s departure comes during an election cycle marked by party-switching. Former Democratic congresswoman Tulsi Gabbard left her party, while former Republican representative Joe Walsh became a Democrat.

In Texas, some Democratic leaders have left their party over immigration policies. Political analysts say these moves reflect changing coalitions within both major parties. Duncan has not indicated whether he plans to seek public office again.
