Hoover's war-time service made him a favorite of many progressives, and he unsuccessfully sought the Republican nomination in the 1920 presidential election. Hoover demanded, and received, authority to coordinate economic affairs throughout the government. He created many sub-departments and committees, overseeing and regulating everything from manufacturing statistics to air travel. Despite the widespread unpopularity of the bill, Hoover felt that he could not reject the main legislative accomplishment of the Republican-controlled 71st Congress. Over the objection of many economists, Hoover signed the Smoot–Hawley Tariff Act into law in June 1930.
