Smith had previously made a quixotic bid for the Democratic nomination at the 1920 Democratic National Convention, where his nomination received an invigorating seconding speech by Franklin Delano Roosevelt, who also served as Smith's floor manager at the 1920 convention. Roosevelt, who had campaigned for Smith's gubernatorial campaign in 1918, was chosen by the New York Democratic Party to second Smith's 1920 bid for the nomination. One contributing factor to this had been Roosevelt's friendly relationship with Tammany Hall leader Charles Murphy While Smith had lost the 1920 nomination, Roosevelt was himself nominated as the vice-presidential running-mate of James M. Cox.
