 Hoover became increasingly conservative in this time, and he strongly criticized Roosevelt's foreign policy and New Deal domestic agenda.In the 1940s and 1950s, Hoover's public reputation was slightly rehabilitated after serving in various assignments for Presidents Harry S. Truman and Dwight D. Eisenhower, including as chairman of the Hoover Commission.Though he managed somewhat to rehabilitate his legacy, Hoover is still widely regarded as an inadequate U.S. president, and most polls of historians and political scientists rank him in the bottom third overall.
