In what year was Warren G. Harding elected?

Warren G. Harding was elected as the 29th President of the United States in the year 1920. His election came after World War I, during a time when the nation was looking for a return to normalcy and stability. Harding campaigned on the promise of reducing the federal government's role in the economy and providing a peace-oriented foreign policy, which resonated with voters eager for a relief from wartime pressures.

The other years listed do not align with Harding's election. For example, 1918 was during the final stages of World War I, while 1922 and 1924 were subsequent to his election, with the latter being the year that Herbert Hoover was chosen to succeed Calvin Coolidge as president. Thus, the correct identification of 1920 as Harding's election year is confirmed by the historical context surrounding his campaign and presidency.
