In 1932, America suffered greatly during the Great Depression. The President at the time, Herbert Hoover, promised many reforms and improvements that would help everyone get back onto their feet. Those promises were broken as Hoover did little to pull America out of the Depression. As a result, Hoover wasn't really well liked, during and after the depression. When the elections of 1932 came around, Hoover decided to run again, but Americans went and voted for Roosevelt, who actually did something to help during the depression.
