I don't think AL-07 or MS-02 is necessarily a problem. If 2011 VA-03 fell, 2011 LA-02 should obviously fall as well. Is it possible to draw 2 majority-black CVAP districts in SC without linking distant metros like VA-03 or LA-02? If so, SC-06 should also fall.
They don’t have to be majority, just have a high enough percentage of African Americans to elect a representative of their choice in both districts. In S.C., you would have one district anchored in Charleston and another in the connecting Columbia and the PeeDee. Both districts would have a Democratic performance in the high 50s and a black percentage in the high 40s.
