'Lifelong Republican' ex-GA lieutenant gov. endorses Kamala Harris

Former Georgia Lieutenant Governor explained in an op-ed published by the Atlanta Journal-Constitution earlier this year why he was supporting President Joe Biden in his bid for reelection.

Skewering his fellow Republicans for "[falling] in line behind Donald Trump," the ex-GOP leader wrote: "The healing of the Republican Party cannot begin with Trump as president," which is why, "This November, I am voting for a decent person I disagree with on policy over a criminal defendant without a moral compass."

Now that Biden has dropped his bid and nominated Kamala Harris for the presidency, Duncan announced his endorsement for the vice president Wednesday.

"I’m committed to beating Donald Trump," Duncan wrote in a post via X. "The only vehicle left for me to do that with is the Democratic Party. If that requires me to vote for, speak for, or endorse @KamalaHarris then count me in!"

MSNBC's Katie Phang responded to the former Georgia leader's post, writing: "From the former Lt. Gov. of Georgia, Geoff Duncan, a lifelong Republican."

Eric Columbus, former counsel to Biden during his years as a senator, wrote: "Duncan was the Georgia Lt. Gov. from 2019-2023. He backed Trump in 2020, but was horrified by Trump's attempted coup. He endorsed Biden in May, and wrote: 'I am voting for a decent person I disagree with on policy over a criminal defendant without a moral compass.'"
