The enemedia is doing it’s best to keep blacks on the democrat plantation. Lewis, Jackson, Obama, and Sharpton are the overseers.
There was a series of books published in the 1960s and 1970s, called The Biographical Dictionary of the Left, that had thumbnail biographies of American leftists from the 19th Century through the time of publication. That would include the period of Lewis's supposed Communist affiliation. I don't have access to these books. However, with CIA chief John Brennan a Muslim convert and a former Communist voter, I would not be surprised if Lewis had been a Communist.
