I thought they DID require a Presidential run-off.
In 1992, CNN took Georgia off its Election Night board because Clinton only won it with 43%. I always assumed that the reason Bush didn't push the runoff was because he was too far behind to win, anyway.
Was it on Bush to call for a run-off?
I don't know. I thought so, but maybe CNN misspoke with regard to their knowledge of GA law.
No it’s just a plurality for presidential elections as highlighted under section F.
