What are opinions on how George W. Bush would rank in a list of the best US Presidents?

Not very good. He currently enjoys one of the lowest approval ratings of any president in his second term. The Iraq war is now largely regarded as a mistake by many political scientists and the majority of the American public. Considering his low approval ratings and the Iraq quagmire, he is likely to end up on the list of nation's least effective and thereby worst presidents. this is a diff. oppinion, i need the actually rank he got... for hw!
