Thomas Edmund Dewey was an American lawyer and politician who served as the 47th governor of New York from 1943 to 1954. He was the Republican Party's nominee for president of the United States in 1944 and 1948, losing the latter to Harry S. Truman in a major upset. The 288 combined electoral votes Dewey received from both elections place him second behind William Jennings Bryan as the candidate with the most electoral votes who never acceded to the presidency.

The 1944 United States presidential election was the 40th quadrennial presidential election. It was held on Tuesday, November 7, 1944. The election took place during World War II, which ended the following year. Incumbent Democratic President Franklin D. Roosevelt defeated Republican Thomas E. Dewey to win an unprecedented fourth term. It was also the fifth presidential election in which both major party candidates were registered in the same home state; the others have been in 1860, 1904, 1920, 1940, and 2016.
