The Clintons have all the political machinery working in their favor in SC. Bernie had no such history there and just appeared to these voters with some abstract message about wall street, not a concrete message about how it is impacting their day to day world.
Bernie was missing that cultural and relational connection, the political machinery, the ground game and his abstract(for them) message. Clinton was always going to win there but people don't seem to get how conservative black people are outside of our own struggles. We vote democrat because the republican party in 2016 is full of racist bigots and people who have zero interest in the black struggle, not because of abortion rights or gay rights. Black people in general are not with the young liberal white voters who are keeping Bernie's hopes alive right now. Hillary is a corporatist shill but none of that matters when they think she is for them, understands them and they matter to her outside of electoral politics. It's really simple. If Bernie has sewn those seeds 20-30 years ago and maintained those networks then things would be different. In Hillary they detect a white woman who at least appears to have made an effort over time, not some carpetbagger with big ideas who is only making that appeal now. Is it fair? Are any social networks and legacies fair? Older Black people trust the clintons but didn't know or trust Bernie. They might not have a grasp on the issues that matter in 2016 but they have their gut and some people are just "gut" people.
