The logical primary challenger to Kemp is Doug Collins.
Kemp went from a hero to a zero. Raffensberger is a bureaucrat who looks like he cucked out with a Consent Decree that he didn't need to sign. This cuck image spread to Kemp when it became clear that he signed off on the Consent Decree relaxing mail-in ballot verification as well. Kemp now looks like a guy who rolled over to Stacey Abrams when he didn't have to. He looks like Stacey Abrams "owned" him. And, in fact, she did; Kemp (and Raffensberger) were owned by a mentally unstable losing candidate who still insists that she won the 2018 election.
Nothing hurts a Gubenatorial candidate more than the appearance of being "weak". Kemp looks weak all around, being pushed around by Stacey Abrams, then being pushed around by Donald Trump. He's hiding in a bit of a Bidenesque way during the present controversy. I would not want to be in Kemp's shoes. His public image has suffered amongst his base, and I would not be surprised if he opts to not run for re-election, or to run for the Senate should Warnock win.
Aren’t Doug Collins and Stacy Abrams actually somewhat friendly with each other outside of politics? I recall hearing that somewhere.
