A recent issue of US News features a story ranking the worst presidents in US history, they also ask readers to rank where George W. Bush would rank.

According to US News the bottom ten are:
1. James Buchanan
2. Warren G. Harding
3. Andrew Johnson
4. Franklin Pierce
5. Millard Fillmore
6. John Tyler
7. Ulysses S. Grant
8. William Harrison
9. Herbert Hoover | Richard Nixon (tie)
10. Zachary Taylor

Quite frankly, is the American public truly capable of adding anything to this list. It would be a fair bet that most Americans know nothing of any of these presidents, with the possible exception of Richard Nixon, and thus could not hope to offer an intelligent assessment. While US News is probably right on the money with the top three, there are a few who are noticeably absent. And why is Harrison in the ranking, he only served 30 days, hardly long enough to do much of anything? Some former presidents have been so glamorized by history, the reality of their colossal failures and misjudgments have been ignored, chief among them being Jefferson and Jackson.

There is no doubt that Bush will be judged poorly in many regards, but he is far from the worst. One future edition that is a foregone conclusion is future President Hillary Clinton, whose leadership of this country promise to eclipse all challengers as the worst in US history.
