Coolidge cabinet
Calvin Coolidge , who in 1920 at the side of Warren G. Harding for Vice President of the United States was elected, moved after Harding's death in 1923 to the post of US president on. In the following year , the Republican used the economic boom in the USA to secure his re-election with a clear margin over the Democratic candidate John W. Davis .
Treasury Secretary Andrew W. Mellon , Secretary of the Post Office Harry S. New, and Secretary of Labor James J. Davis, three members who had served under President Harding remained in cabinet until the end of Coolidge's presidency in 1929. His successor was Herbert Hoover , who had been Secretary of Commerce for many years , after Coolidge refused to run again in the 1928 election .
