Coolidge captured the vice presidential nomination for the Republican Party on the first ballot. Warren G. Harding emerged as the presidential candidate. After Harding won the election, Coolidge served as vice president. At this election, the Democrats nominated James Cox as their presidential candidate and New York politician Franklin D. Roosevelt as their vice president. Roosevelt would go on to become the longest serving president in U.S. history. As vice president, Coolidge rarely intervened in Senate affairs, though he enjoyed presiding over them and listening to the debates. It was because of his hands-off approach that he earned the nickname “Silent Cal.”
