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.
Mississippi has an extremely polarized voting. To get even 20% of white vote for Democratic candidate is very difficult (almost impossible in most cases) task.There are some exceptions, but they are exactly that - exceptions. Even formerly "populist" (but, usually, very social conservative) NE Mississippi now votes heavily Republican on Presidential, statewide and Congressional level.
