Wow, nice map, Kal! It's almost too overwhelming for me to take much from it at first, haha. The Roosevelt support in Mississippi and Alabama seems surprising, though I guess this is still at the time when there was still a heavy stigma for anyone with that "R" next to his name in the South.
Thank you
I'm sorry for not being able to find detailed results for TX and GA.
Results from the Solid South can be a bit confusing. For example, we see a TR or Debs-colored county in South Carolina here, but it usually meant they received a handful of votes. You notice that very few people turned out for general elections in South Carolina during the Solid South days, and not just in presidential election, as opposed to primaries. In 1912 Wilson took 95.94% of the SC vote, but in absolute numbers it meant just 48,355 people voting.
To put it in perspective, a hotly contested 1938 Democratic senatorial primary between "Cotton Ed" Smith and Olin D. Johnston saw 337,016 people turning to vote, of which only 45,861 turned up in November.
Interestingly Debs actually came in second in Florida, even though he only got 9.45%, as opposed to Wilson's 69.52%. Still, I believe that was the only state ever where a Socialist Party nominee took the silver. That is unless you discount 1924 La Follette's performance in California (he ran as Socialist there, similarly to being a NPL candidate in North Dakota).
