After making an airplane trip to the Democratic convention, Roosevelt accepted the nomination in person. In his speech, he stated, "ours must be a party of liberal thought, of planned action, of the enlightened international outlook, and of the greatest good to the greatest number of our citizens." Roosevelt's trip to Chicago was the first of several successful, precedent-making moves designed to make him appear to be the candidate of change in the election. Large crowds greeted Roosevelt as he traveled around the nation; his campaign song "Happy Days Are Here Again" became one of the most popular in American political history – and, indeed, the unofficial anthem of the Democratic Party.
