The third and fourth terms
The swap of ships for bases took place during the 1940 presidential election campaign. Earlier in the year the Democrats had nominated Roosevelt for a third term, even though his election would break the two-term tradition honoured since the presidency of George Washington. The Republican nominee, Wendell L. Willkie, represented a departure from the isolationist-dominated Republican Party, and the two candidates agreed on most foreign-policy issues, including increased military aid to Britain. On election day, Roosevelt defeated Willkie soundlyby 27 million to 22 million popular votesthough his margin of victory was less than it had been in 1932 and 1936. Roosevelt's support was reduced by a number of factors, including the court-packing scheme, the attempted purge of conservative Democrats in 1938, the breaking of the two-term tradition, and fears that he would lead the nation into war. (See primary source document: Third Inaugural Address.)
By inauguration day in 1941, Britain was running out of cash and finding it increasingly difficultowing to German submarine attacksto carry American arms across the Atlantic. In March 1941, after a bitter debate in Congress, Roosevelt obtained passage of the Lend-Lease Act, which enabled the United States to accept noncash payment for military and other aid to Britain and its allies (see primary source document: Proposal for Lend-Lease). Later that year he authorized the United States Navy to provide protection for lend-lease shipments, and in the fall he instructed the navy to shoot on sight at German submarines. All these actions moved the United States closer to actual belligerency with Germany.
In August 1941, on a battleship off Newfoundland, Canada, Roosevelt and British Prime Minister Winston Churchill issued a joint statement, the Atlantic Charter, in which they pledged their countries to the goal of achieving the final destruction of the Nazi tyranny. Reminiscent of the Four Freedoms (see original text) that Roosevelt outlined in his annual message to Congress in January 1941, the statement disclaimed territorial aggrandizement and affirmed a commitment to national self-determination, freedom of the seas, freedom from want and fear, greater economic opportunities, and disarmament of all aggressor nations.
