I propose that we gather together historical facts and engage in 'friendly' (you don't have to be friendly but remember that ultimately this is a bit about shitting on awful awful people) debate to decide who was the worst President in the history of the United States of America.
Surprised that Truman isn't at least in the running. I'm probably being delusional, but it feels like there was a moment after WWII that seriously good things could have happened if the USA didn't fasc-it the bed. Not to mention the nukes...
