The first few primaries set the tone for much of the rest of the election. The inention is to move the first primary to a state that is more racially diverse and representative of the country as a whole. NH is 92% white, 2.7% asian and 1.55% black. SC is 69% white and 27% black and 2% asian. Nationally, the racial makeup is 75.8% white, 13.6% black and 6.1% asian. Obviously SC isn't a perfect choice but has more diversity than NH.
