During this period, he also served as chairman of the Non-Partisan Railroad Commission, an entity created by several banks and corporations to survey the country's long-term transportation needs and make recommendations for improvements. He was an honorary president of the American Foundation for the Blind, a director of New York Life Insurance Company, president of the American Antiquarian Society, and a trustee of Amherst College.[180]
Coolidge published his autobiography in 1929 and wrote a syndicated newspaper column, "Calvin Coolidge Says", from 1930 to 1931.[181] Faced with a Democratic landslide in the 1932 presidential election, some Republicans spoke of rejecting Hoover as their party's nominee, and instead drafting Coolidge to run. Coolidge made it clear that he was not interested in running again, and that he would publicly repudiate any effort to draft him.[182] Hoover was renominated, and Coolidge made several radio addresses in support of him. Hoover then lost the general election to Coolidge's 1920 vice presidential Democratic opponent Franklin D. Roosevelt in a landslide.[183]
