With Roosevelt not committed to keeping or dropping Wallace, the vice-presidential balloting turned into a battle between those who favored Wallace and those who favored Truman. Wallace did not have an effective organization to support his candidacy, though allies like Calvin Benham Baldwin, Claude Pepper, and Joseph F. Guffey pressed for him. Truman, meanwhile, was reluctant to put forward his own candidacy, but Hannegan and Roosevelt convinced him to run. At the convention, Wallace galvanized supporters with a well-received speech in which he lauded Roosevelt and argued that "the future belongs to those who go down the line unswervingly for the liberal principles of both political democracy and economic democracy regardless of race, color, or religion". After Roosevelt delivered his acceptance speech, the crowd began chanting for the nomination of Wallace, but Samuel D. Jackson adjourned the convention for the day before Wallace supporters could call for the beginning of vice presidential balloting. Party leaders worked furiously to line up support for Truman overnight, but Wallace received 429 1/2 votes (589 were needed for nomination) on the first ballot for vice president and Truman 319 1/2, with the rest going to various favorite son candidates. On the second ballot, many delegates who had voted for favorite sons shifted into Truman's camp, giving him the nomination.
