New York Gov. Thomas E. Dewey, Republican nominee for president, waved to the crowd after arriving at Union Station in downtown Lexington on October 12, 1948. Dewey, accompanied by his wife, Frances, was on a one-day campaign swing through the state. The governor spoke for approximately 20 minutes to a crowd estimated from 4,500 to 7,500. Dewey was running against incumbent President Harry S. Truman, became president after the death of President Franklin D. Roosevelt in 1945. The election, which Truman won, was considered the greatest election upset in American history. Virtually every prediction indicated that Truman would be defeated by Dewey. Truman received 49.6 percent of the popular vote, while Dewey had 45.1 percent. Herald-Leader Archive Photo
