PBS is hosting a Democratic presidential debate in Wisconsin tonight. This comes as Clinton is expected to pick up a key endorsement from the political action committee, or PAC, of the Congressional Black Caucus today. Hillary Clinton is also expected to campaign next week with Geneva Reed-Veal, the mother of Sandra Bland, the 28-year-old African-American woman who was found hanged in her jail cell three days after a white Texas state trooper arrested her in July for allegedly failing to signal a lane change. Meanwhile, Michelle Alexander has written a seething critique of Hillary Clinton, published yesterday by The Nation magazine. Alexander, the author of "The New Jim Crow," argues Clinton does not deserve the black vote, pointing to her role in advocating for the passage of the 1994 crime bill, as well as the 1996 Welfare Reform Act. Alexander writes: "It is difficult to overstate the damage that’s been done. Generations have been lost to the prison system; countless families have been torn apart or rendered homeless; and a school-to-prison pipeline has been born that shuttles young people from their decrepit, underfunded schools to brand-new high-tech prisons. ... Hillary believes that she can win this game in 2016 because this time she’s got us, the black vote, in her back pocket—her lucky card. She may be surprised to discover that the younger generation no longer wants to play her game."
