MLK endorsed Lyndon Johnson for President? Does that make him a Conservative?

Coretta Scott King, My Life with Martin Luther King, Jr. (1969), is his wife's account. Other biographies include Lerone Bennett, Jr., What Manner of Man (1964); William Robert Miller, Martin Luther King, Jr. (1968); Charles Eric Lincoln, Martin Luther King (1969); and David L. Lewis, King: A Critical Biography (1970), written by a young black historian. An unfavorable view of King and his work is Lionel Lokos, House Divided: The Life and Legacy of Martin Luther King (1968).
