[rogue yam]

Lots of people have made the same comment on FR, but none have given a definitive explanation of how voters knew Greene was black when he had no ads and gave no interviews.

I don't know about "definitive explanations" but I have seen it repeatedly posited here on FR and elsewhere that a typical black South Carolinian looking at the two names "Alvin Greene" and "Vic Rawl" would conclude that the former was much more likely to be black than the latter.

This makes sense to me.
