June 25, 1948:
At their national convention in Philadelphia, Republicans nominate New York Gov. Thomas Dewey for president and California Gov. Earl Warren for vice president.
Dewey defeats Sen. Robert Taft of Ohio and former Minnesota Gov. Harold Stassen, among others, to win the nomination on the third ballot. Dewey was also the GOP presidential nominee in 1944, losing to President Franklin D. Roosevelt. In a surprise, he will go on to lose this year's election as well, to President Harry Truman.
