racial demographics are not destiny
the only thing the concept of blue mississippi has going for it is that the state is becoming less white but even then 1) so is the rest of country and 2) minorities in the state would have to maintain their support for democrats for the next several decades until the actual composition of the population that votes becomes majority-minority
texas is a more plausible case because 1) the vast majority of the growth is actually happening in urban, blue/blue-trending areas and 2) college grads are moving there at high rates
Actually no if Dems can reduce GOP share of the white vote in MS to 65% they will win the state
