Presidential elections were held on Tuesday, November 7, 1944. The election took place during World War II which ended the following year. The Democratic ticket of incumbent President Franklin D. Roosevelt and Senator Harry Truman defeated the Republican ticket of New York Governor Thomas E. Dewey and Ohio Governor John Bricker 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. Though the margin of victory was still a landslide, this was Roosevelt's weakest performance in his four elections, and the popular vote split was less lopsided.
Roosevelt had become the first president to win a third term with his victory in the 1940 presidential election, with little doubt that he would seek a fourth term. Unlike in 1940, Roosevelt faced little opposition within his own party, and he easily won the presidential nomination of the 1944 Democratic National Convention. Concerned that Roosevelt's ill health would mean the vice president would likely become president, the convention dropped Roosevelt's vice president Henry A. Wallace in favor of the lesser known Senator Harry S. Truman of Missouri. Governor Dewey of New York emerged as the front-runner for the Republican nomination after his victory in the Wisconsin primary, and he defeated conservative Governor John W. Bricker at the 1944 Republican National Convention.
