A former Republican politician just made a decision that will surely piss off President Donald Trump.

Former Georgia Lt. Gov. Geoff Duncan announced on Tuesday that he has left the GOP and officially joined the Democratic Party.

Duncan, who served as lieutenant governor from 2019 to 2023, made the announcement official in an Atlanta Journal-Constitution op-ed headlined “From Republican Lt. Governor To Democrat: Loving My Neighbor Is Easier Now.”

In the piece, Duncan said that the switch was a long time coming, starting “well before” Trump “tried to steal the 2020 election in Georgia,” but he admitted there wasn’t any “date on a calendar or line in the sand that points to the exact moment in time” he made up his mind to become a Democrat.

Duncan said his decision was “centered around my daily struggle to love my neighbor, as a Republican.”
