Shua you was close to my original worst case map I came close to posting. Well done
I can see AIP getting a lot of votes in the deep south due to Lester Maddox being on the ticket, he could have a bit of fresh air to attack Carter as they didn't like each other from the time Carter was governor. I could see him maybe passing Carter in Alabama if Wallace endorsed him. That's a possibility (maybe more distant than in 68 or 72,) that he wouldn't support Jimmy if he picked her. But than again he was sociable with Chisholm so who knows.
Interesting scenario though.
