The Root has the article Why Most Black Voters Still Aren’t Feeling Bernie Sanders.

Still, there’s something in the way he’s doing it that’s not clicking with most African-American voters. This isn’t an argument against Sanders. It’s genuine fascination with his dilemma, because no candidate can win the Democratic nomination without the black vote. Despite memorable debate lines and cover for an email-embattled Clinton, Sanders didn’t really budge all that much with black voters. Here are three main reasons that’s the case … and why it probably stays that way:

Even on the Tavis Smiley interview, Bernie Sanders immediately went to the economic issues as the reason why black voters should support him. For once in his life, maybe he could start out with BLM and Sandra Bland before he gets to economic issues and high rates of incarceration.

The anger issue comes up in thie article in a slightly different way.

2. Bernie should watch more black pastors on Sunday. While it’s still anecdotal, the core of Sanders’ black-voter problem could be this: He’s too depressing. Comedian Larry David couldn’t resist the temptation in last week’s SNL skit to call out Sanders’ aggressive “the sky is falling” ethos.

For sure, African-American voters generally love the public figures who claim to “keep it real” and cast rebellious shade at the “system.” But candidates who successfully woo black constituencies are those who can illustrate hope.

Sure, the black interruptions at the Sanders events have displayed a lot of anger. That’s only the side of the discussion that we have seen. There are other facets to the discussion.
