Dewey was also the GOP’s nominee for President in 1944, but was defeated by Franklin D. Roosevelt, who secured an unprecedented fourth term during World War II.

Dewey chose two-term Governor Earl Warren of California as his running-mate. Warren was nominated unopposed the next day, on June 25, 1948.
