Clinton campaigned hard in the state, drawing large, mostly African-American crowds to town halls and rallies across South Carolina. (ABC exit polling showed that Clinton won 84 percent of the black vote.) She stressed her personal commitment to the state, which she first visited as a young lawyer fighting against a system that sent juveniles to adult jails, and slammed Sanders on gun control in particular. She campaigned with African-American mothers whose children were killed by police or as a result of gun violence, and made reforming the criminal justice system and ending “systemic racism” a centerpiece of her stump speech.
