Seems okay. South Carolina is a Republican base state and a reasonably good microcosm of the party for their primary.
For Democrats, South Carolina is a test run for how the presidential candidates are doing with the black vote. This is very important for us. Is there some other state which could fill that role better?
Nevada would be the best for either party to do number 1. Includes the least chance a Warren or Cruz candidate can win due to the lack of that upscale base for either party. Also has a relatively diverse population.
