I could see Mississippi going Dem before Alabama.
Alabama has a larger population of "populist"-leaning white voters who might, theoretically, at some point in the future, be more inclined to support a Democratic presidential candidate. Alabama also has a larger population of socially "moderate" (not "moderate" in the normal sense of the term, but not proudly racist) suburban whites who might, theoretically, etc.
Not in the South. Georgia is full of those "moderate" types, and they're the strongest Republican voters in the state.
