I don't think it's hopeless-- her numbers are down overall since her first term:

Greene ran for re-election after winning a legal challenge to her eligibility based on her alleged involvement in organizing and promoting the 2021 United States Capitol attack, based on the Fourteenth Amendment to the United States Constitution, which bars people who have engaged in insurrection from serving in Congress. While Greene won by a comfortable margin, this was the worst showing ever by a Republican in the 14th district, and the best performance of a Democrat in this district, being the first time since the district was created that the Democrat received more than 28% of the vote.

So while a dem is never getting that seat, it could be an indication that she's losing support overall from her base, who just might be tired of her shit and want a more competent republican to fuck them over instead. Most of the people she beat in the 2022 primaries sound at least a little more impressive than part time crossfit coach and conspiracy nutjob, so maybe someone else will have a chance in November.

GOP primary 2022:

Eric Cunningham, sales executive
James Haygood, farmer
Charles Lutin, physician and veteran
Jennifer Strahan, CEO of J. Osley & Co.
