Try James Buchanon.
He pretty much dropped the ball and let the chain of events that started the Civil War.
One fun poll...

My line of reasoning goes like this...
You sucked as a president if people rank you below William Henry Harrison.
I doubt Clinton will be there... Bush... probably will be there for about 10 years... then float up to the bottom middle of the pack... people will probably be more forgiving of him in the future.
The war in Iraq won't look so bad when people are a bit backed off from it... assuming that Iraq stays stable and a better place then when Saddam ruled it.
