Former Georgia Republican Lt. Gov. Geoff Duncan on Monday said he will vote for President Joe Biden in November, arguing former President Donald Trump “has disqualified himself through his conduct and his character.”

“Unlike Trump, I’ve belonged to the GOP my entire life. This November, I am voting for a decent person I disagree with on policy over a criminal defendant without a moral compass,” Duncan, a CNN contributor, wrote in an opinion piece published in the Atlanta Journal-Constitution.

Duncan told CNN’s Laura Coates Monday night that Trump “is not a Republican” and “doesn’t represent our brand.”

“Donald Trump’s not a Republican. He doesn’t represent our brand. He doesn’t represent our future. He’s a horrible human being at this point, we’re watching that play out hour by hour in the courtroom,” Duncan said. “It’s time to move on. If we’re going to heal as a party and truly get back to doing the things that we should do – and that’s be conservative but not angry or crazy or liars – we should turn the page immediately from Donald Trump.”

In the op-ed titled, “Why I’m voting for Biden and other Republicans should, too,” Duncan outlined why he has decided against backing the GOP nominee. While Duncan admitted Biden’s age is a concern for many and his “progressive policies aren’t to conservatives’ liking,” he wrote he was left with no alternative as he argued a second Trump term would hinder the Republican Party from moving forward.
