According to the 2010 census, the population of Mississippi is
58% White
37% Black
5% Other (Hispanic+Asian+Native)
If 95% of the blacks and 70% of the other vote Democratic, it is necessary that only 19,6% of the whites vote Democratic in order to have a tied election. Why wouldn't a Democratic candidate in the future have this percentage?
Much was talked about Texas and Arizona becoming swing states because of the hispanic population. But the blacks are much more loyal to the Democratic Party than the hispanic.
And in 2012, Obama was better in Mississippi than he was in Texas.
37% black population =/= 37% of the electoral roll is black =/= 37% of those who turn out and vote are black
