The situation that most contributed to Roosevelt's landslide win in 1932 was "Hoover's policies failed to provide sufficient economic relief."
Americans were upset with President Hoover because he basically did nothing to help the poor and the ones in need during the Great Depression. Let's remember that the US stock market exchange crashed on October 29, 1929, starting the period known as the Great Depression, in which many citizens lost their jobs, banks went into bankruptcy, and companies closed. So Hoover's immobility to help the ones in need open the door to Franklin D. Roosevelt and his series of programs called "New Deal" aimed to help people overcome adversity.
