I went for AL, AR, GA, LA, MS, SC
This is exactly what I chose. I considered adding FL because it's to the south of all those states, but it's always been less race-consious or 'southern' as the other states (with the possible exception of Northern Florida). It's much less white than the other Deep South states, excluding GA. (By the way, I would say the current Deep South no longer includes Georgia, where most of the state retains remnants of a 'Deep South' culture, but where half the population is concentrated in the Atlanta metropolitan area alone. No other Deep South State is as urban as GA, so in a historic and geographic sense, yes, it's technically a 'Deep South' state, but for all practical purposes, it's not much more 'Deep South' than FL.)
