<P> The first presidential candidate to choose his vice presidential candidate was Franklin D. Roosevelt in 1940 . The last not to name a vice presidential choice , leaving the matter up to the convention , was Democrat Adlai Stevenson in 1956 . The convention chose Tennessee Senator Estes Kefauver over Massachusetts Senator ( and later president ) John F. Kennedy . At the tumultuous 1972 Democratic convention , presidential nominee George McGovern selected Senator Thomas Eagleton as his running mate , but numerous other candidates were either nominated from the floor or received votes during the balloting . Eagleton nevertheless received a majority of the votes and the nomination , though he later resigned from the ticket , resulting in Sargent Shriver becoming McGovern 's final running mate ; both lost to the Nixon - Agnew ticket by a wide margin , carrying only Massachusetts and the District of Columbia . </P>
