In 1928, Herbert Hoover won the Presidency. Over the next four years he presided over the Great Depression, the Smoot Hawley tariff act, he had the army attack a homeless camp made up of World War One veterans and their families, over 6,500 banks shut down between 1929-1933 which cost millions of people their life savings, the Nazis came to power in Germany… and, despite this, Hoover still received 75% of his 1928 vote count in November 1932.
What can I say, other than the majority of Republican voters do not vote on the basis of reality but of tribal identity?
