Whenever blacks become a majority there.
Actually, this makes sense. Blacks will likely become the majority in Mississippi in the 2040s, maybe even sooner than that. It'll happen sooner than most think, I think.
After eating my humble pie, I have to say: excuse me?
The proportion of Black people in Mississippi is currently growing at a rate of about 1 percentage point every decade. They are currently 38% of the population. What in the hell do you think will happen to make Mississippi a Black majority state within 20-something years?
