After President Calvin Coolidge announced in August 1927 that he would not seek a second full term of office in the 1928 presidential election , Hoover emerged as the front-runner for the Republican presidential nomination . While Hoover gained the support of important party constituencies and won several primaries , many party leaders opposed his candidacy . Coolidge viewed Hoover 's candidacy with ill-concealed disgust , on one occasion remarking that " for six years that man has given me unsolicited advice — all of it bad . " Even so , Coolidge had no desire to split the party by publicly opposing the popular Commerce Secretary 's nomination . Hoover 's opponents were unable to unite around an alternative candidate , and Hoover won the presidential nomination on the first ballot of the 1928 Republican National Convention . The delegates considered re-nominating Vice President Charles Dawes to be Hoover 's running mate , but Coolidge , who hated Dawes , remarked that this would be " a personal affront " to him . The convention instead selected Senator Charles Curtis of Kansas
