The 1956 National Convention of the Democratic Party nominated former Governor Adlai Stevenson of Illinois for President and Senator Estes Kefauver of Tennessee for Vice President. It was held in the International Amphitheatre on the South Side of Chicago, Illinois August 13–August 17, 1956. Unsuccessful candidates for the presidential nomination included Governor W. Averell Harriman of New York, Senator Lyndon B. Johnson of Texas, and Senator Stuart Symington of Missouri.
As the unsuccessful 1952 Democratic Party presidential nominee, Stevenson had the highest stature of the active candidates and was easily renominated on the first ballot. Former President Harry S. Truman, whose support for Stevenson in '52 helped secure him the nomination, was opposed to his renomination in 1956, instead favoring Harriman. It did no good, as Truman was no longer a sitting President, and Stevenson was nominated on the first ballot.
After Stevenson decided not to reselect his 1952 running mate John Sparkman, the convention was marked by a "free vote" for the vice presidential nomination in which the winner, Kefauver, defeated Senator John F. Kennedy of Massachusetts. The vice presidential nomination vote, which required three separate ballots, was (as of 2016) the last multi-balloted contest held at a quadrennial political convention of any major U.S. political party for the presidency or vice presidency.
The Democratic convention preceded the Republican convention in the Cow Palace, San Francisco, California. At the GOP gathering, President Dwight D. Eisenhower was nominated for reelection.
1956 Democratic National Convention Wikipedia
The Democrats favored greater reliance on the United Nations, multilateral disarmament, more spending for programs relating to social welfare and agriculture, "a full and integrated program of development, protection, management and conservation of natural resources" and the use of peaceful atomic energy
With regard to the growing issue of civil rights, the platform called for voting rights, equal employment opportunities, and the desegregation of public schools.
The roll call, as reported in Richard C. Bain and Judith H. Parris, Convention Decisions and Voting Records, pp. 294–298:
The highlight of the 1956 Democratic Convention came when Stevenson, in an effort to create excitement for the ticket, made the surprise announcement that the convention's delegates would choose his running mate. This set off a desperate scramble among several candidates to win the nomination. A good deal of the excitement of the vice-presidential race came from the fact that the candidates had only one hectic day to campaign among the delegates before the voting began. The two leading contenders were Senator Kefauver, who retained the support of his primary delegates, and John F. Kennedy, who, as a first term Senator from Massachusetts, was relatively unknown at that point. Kennedy surprised the experts by surging into the lead on the second ballot; at one point he was only 15 votes shy of winning. However, a number of states then left their "favorite son" candidates and switched to Kefauver, giving him the victory. Kennedy then gave a gracious concession speech. The narrow defeat raised his profile and helped Kennedy's long-term presidential chances, yet by losing to Kefauver he avoided any blame for Stevenson's expected loss to Eisenhower in November. As of 2017, this was the last time any presidential or vice presidential nomination of either the Democratic or Republican parties, went past the first ballot.
The vote totals in the vice presidential balloting are recorded in the following table, which also comes from Bain & Parris.
On November 6, Adlai Stevenson and Estes Kefauver lost the election to President Eisenhower and Vice President Nixon in a landslide.
