Given the climate, voting restrictions put into place in GA post-2020 and Trump's instigating against Kemp (and in the opposite direction, continuing demographic shift), I'd lean toward yes. Unlike some and in the worst-case scenario, I don't believe that an Abrams loss will be statistically larger than it was in 2018 - and as we saw in the runoffs, Trump's rainclouds over everything contributed potentially one point or more in favor of Warnock and Ossoff.
However, it's just as likely that demographic shift contributes as much or more as anything Trump says or does. Now, if he were
somehow petty enough to endorse Abrams outright...
whew.
