Don't forget Mississippi. It trended Democratic a bit last year so it'll be a Democratic lock by 2016. By 2018 we should just focus on holding the Idaho and Wyoming governorships because all of the other states will have tossed the RepubliKKKans.
By 2036 it will probably will be, assuming current demographic trends and blacks staying over 98% Democratic.
Ah yes and by then something will have happened to stop the trend. Have you ever seen a trend go on forever? Even for over 30 years it's hard to come by. Remember it's been trending since 2008.
Well unless Democrats start saying that black people aren't people, blacks will vote 85+% for Democrats, and they have since the 60's, ever since the Civil Rights Act. It is certain that the white population will decline and the black population will grow substantially, especially in Mississippi. The changes will make this red state blue. Not now, not next year, hell not even in the next 20 years. But in 2036 or 2040, Democrats can put this state in the lean column.
