The general election (Nov. 4) is not referred to as a primary in Georgia - that's only a Louisiana thing.
That's certainly an interesting scenario, but the vast majority of votes are done being counted by the end of the week - usually, even if every uncounted ballot broke to the leading candidate, it still wouldn't put them over the top.
That's how it happens in Georgia, usually. Of course, there could always be a possibility of it being extremely close, but I think that's better left to the fantasy storylines on here.
