Not sure how I missed this yesterday, but with the new Gallup poll, George W. Bush has passed Nixon and Truman, and become the least popular President of all-time. According to the Roper Center, here is the worst net approval / disapproval result for every President in the Gallup poll since it began public polling in the late 1930's:
Bush has both the highest overall disapproval, and the lowest overall net approval / disapproval in any Gallup poll taken, ever. Keep in mind that this is a poll that has been functioning for more than 71 years. Also, it should be noted that it is possible that President Taft, who only received 23% of the vote in his 1912 re-election campaign, was more unpopular than Bush, but there weren't public polls back then.
The whole thing makes you long after a parliamentary system of government. That we have been forced to put up with Bush despite his low disapproval for so long strikes me as a flaw in our electoral system.
