In other words, you have no idea what those stats are. I see you’re not interested in anything else but repeatedly harping on 1936 and refuse to address all the other points, especially about whom and where those were allowed to vote and the dynamics at work. Let me know when you’re ready to have more than a simplistic and pointless discussion, otherwise have a nice day.
You held up a 99% SC vote and 97% Miss. vote in 1936 as proof of some kind for explaining why FDR got 71% of the black vote in 1936, why doesn't that explanation work for 1932, and 1948 for instance?
"Or are you going to tell me states like Mississippi voting 97% or South Carolina voting 99% (!) for FDR in 1936 was mainstream ?"
Those two states voted exactly the same in 1932, but Roosevelt only got 23% of the black vote in 1932, what happened?
In 1948 Mississippi went 10% Democrat, and South Carolina went 24% Democrat, yet blacks still voted almost 80% Democrat that year, what happened?
