However, during the campaign against Roosevelt, Dewey broke with Jaeckle over strategy. As Jaeckle recalled in a 1971 interview with The Buffalo Evening News, "I played the game until after the election, then I quit as state chairman." The two men later reconciled, and Dewey asked Jaeckle to join his 1948 presidential run against incumbent Democrat Harry S. Truman. Jaeckle agreed and served as Dewey's floor manager at the 1948 Republican National Convention. During the general election campaign, Jaeckle rode the campaign train with Dewey and did most of his political work.
