Although King never publicly supported a political party or candidate for president, in a letter to a civil rights supporter in October 1956 he said that he was undecided as to whether he would vote for
Adlai Stevenson or
Dwight Eisenhower, but that "In the past I always voted the Democratic ticket."
[63] In his autobiography, King says that in 1960 he privately voted for Democratic candidate
John F. Kennedy: "I felt that Kennedy would make the best president. I never came out with an endorsement. My father did, but I never made one." King adds that he likely would have made an exception to his non-endorsement policy for a second Kennedy term, saying "Had President Kennedy lived, I would probably have endorsed him in 1964."
[64] In 1964, King urged his supporters "and all people of goodwill" to vote against Republican Senator
Barry Goldwater for president, saying that his election "would be a tragedy, and certainly suicidal almost, for the nation and the world."
[65] King supported the ideals of democratic socialism, although he was reluctant to speak directly of this support due to the anti-communist sentiment being projected throughout America at the time, and the association of socialism with communism. King believed that capitalism could not adequately provide the basic necessities of many American people, particularly the African American community.
