This 8 March 2020 video about the USA says about itself:
Earlier today in Michigan the Reverend [former Democratic party presidential candidate] Jesse Jackson endorsed Bernie Sanders, arguing that his path for progressive economic and social justice was the only one to bring equality to the most marginalized people in the United States. As Jesse Jackson noted, [so called] moderate politics won’t bring justice for black Americans ever.
This also matters because Bernie Sanders in the 1980s endorsed Jesse Jackson’s Rainbow Coalition, which in many ways tried to do what Bernie is doing: build a multiracial working-class coalition to challenge the status quo.
Meanwhile, Kamala Harris has endorsed Joe Biden, despite the fact that she has rightfully called out his backward views with regard to racial equality.
Her endorsement was cynical; Jesse Jackson’s was genuine.
