This is blatant pandering to blacks and if Clinton did it she'd be attached mercilessly.
Like I said before:
What an unbelievably patronising thread. Hardly any better than the "still on the plantation" rhetoric you hear from the right. The idea that black people will vote for someone just because you show people a couple of pictures of them and Jesse Jackson together is patently absurd and takes the audience for easily swayed simpletons.
It's clear that Sanders' approach to appealing to black voters is highly superficial and will not work.
Sanders developing a platform on criminal justice reform, like the hiring of his spokesperson, precedes the interruption of his Seattle speech. It might not be enough- probably not- but it's not superficial nor is it inconsistent with his record. (He and Ted Cruz are probably the most consistent candidates running.) Also, I don't see any sign of black voters at large having any negative feelings about Sanders, as opposed to just being more aware of and positive toward Clinton.
