The Republican Convention was held on June 10–12, 1924, in Cleveland, Ohio; Coolidge was nominated on the first ballot. Coolidge's nomination made him the second unelected president to win his party's nomination for another term, after Theodore Roosevelt. Prior to the convention, Coolidge courted progressive Senator William Borah to join the ticket, but Borah refused to relinquish his Senate seat. Republicans then nominated Lowden for vice president on the second ballot, but he also declined. Finally diplomat and banker Charles G. Dawes was nominated on the third ballot.
