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.
You can add that TR actively campaigned in Dixie in 1912 (appalling many of his supporters, who thought, probably correctly, that it was a colossal waste of time and resources that could go to winnable states).
