Worst President Ever?

"In 2004, George Mason University polled 415 presidential historians and found 80 per cent considered Bush's first term a failure. More than half considered it the worst presidency since the Great Depression. More than a third called it the worst in 100 years. Eleven per cent said it was the worst ever. Robert McElvaine, a professor of history at Millsaps College in Mississippi, says scores would likely be worse if the poll were repeated today."

Steve Maich in Macleans magazine attempts an answer.
