No matter how much his backers forced Hillary Clinton’s support of the 1994 crime bill down our throats, he never could steal enough black votes from her. She went on to win the primary with more than
75 percent of their support, compared with just 23 percent going to Sanders. My
own reporting found that some of Sanders’ senior black staffers felt that the campaign—or “the white boys,” as some of the black staffers referred to top campaign staffers—did not take Super Tuesday seriously and were convinced that fighting for black Southern voters was pretty much a lost cause.
And it showed. Sanders was crushed Super Tuesday, with Clinton winning black female voters over with more than
85 percent of the vote in most states. Sanders and his supporters assumed that black voters would be easily drawn to his economic-justice policies. On paper, they were pretty impressive and should have had black women on the fence. Though, when challenged on how his policies would specifically help black people in prime-time moments, he faltered. Badly."
