Incumbent Vice President John Nance Garner opposed Roosevelt's re-election, so the party had to choose a new vice presidential nominee. Roosevelt asked Secretary of State Cordell Hull to serve as his running mate, but Hull preferred to remain in his Cabinet position. Roosevelt's aides also strongly considered South Carolina Senator James F. Byrnes, but the president settled on Secretary of Agriculture Henry A. Wallace. James Farley was considered, but was not selected, because both he and Roosevelt were from New York State; if they had run together, the electors from New York could not have voted for both, in keeping with the terms of the Twelfth Amendment to the Constitution. Others considered were Kentucky Senator Alben Barkley, Supreme Court Justice William O. Douglas, and Speaker of the United States House of Representatives William B. Bankhead of Alabama.
