1940 Republican National Convention in the context of "Liberty Bell"

Wendell Lewis Willkie (born Lewis Wendell Willkie; February 18, 1892 – October 8, 1944) was an American lawyer, corporate executive and the 1940 Republican nominee for president of the United States. Willkie appealed to many convention delegates as the Republican field's only interventionist: although the U.S. remained neutral prior to Pearl Harbor, he favored greater U.S. involvement in World War II to support Britain and other Allies. His Democratic opponent, incumbent President Franklin D. Roosevelt, who had made campaign pledges against U.S. involvement in World War II, won the 1940 election with about 55% of the popular vote and took the electoral college vote by a wide margin.

Willkie was born in Elwood, Indiana, in 1892; both his parents were lawyers, and he also became one. He served in World War I but was not sent to France until the final days of the war, and saw no action. Willkie settled in Akron, Ohio, where he was initially employed by Firestone, but left for a law firm, becoming one of the leaders of the Akron Bar Association. Much of his work was representing electric utilities, and in 1929 Willkie accepted a job in New York City as counsel for Commonwealth & Southern Corporation (C&S), a utility holding company. He was rapidly promoted, and became corporate president in 1933. Roosevelt was sworn in as U.S. president soon after Willkie became head of C&S, and announced plans for a Tennessee Valley Authority (TVA) that would supply power in competition with C&S. Between 1933 and 1939, Willkie fought against the TVA before Congress, in the courts, and before the public. He was ultimately unsuccessful, but sold C&S's property for a good price, and gained public esteem.

Presidential elections were held in the United States on November 5, 1940. The Democratic ticket of incumbent President Franklin D. Roosevelt and Secretary of Agriculture Henry Wallace defeated the Republican ticket of businessman Wendell Willkie and senator Charles McNary to be reelected for an unprecedented third term in office. Until 1988, this was the last time in which the incumbent's party won three consecutive presidential elections. It was also the fourth presidential election in which both major party candidates were registered in the same home state; the others have been in 1860, 1904, 1920, 1944, and 2016.

The election was contested in the shadow of World War II in Europe, as the United States was finally emerging from the Great Depression. Roosevelt did not want to campaign for a third term initially, but was driven by worsening conditions in Europe. He and his allies sought to defuse challenges from other party leaders such as James Farley and Vice President John Nance Garner. The 1940 Democratic National Convention re-nominated Roosevelt on the first ballot, while Garner was replaced on the ticket by Secretary of Agriculture Henry A. Wallace. Willkie, a dark horse candidate, unexpectedly defeated conservative Senator Robert A. Taft and Manhattan District Attorney Thomas E. Dewey on the sixth presidential ballot of the 1940 Republican National Convention.
