President Bush often argues that history will vindicate him. So he can't be pleased with an informal survey of 109 professional historians conducted by the History News Network. It found that 98 percent of them believe that Bush's presidency has been a failure, while only about 2 percent see it as a success. Not only that, more than 61 percent of the historians say the current presidency is the worst in American history. In 2004, only 11.6 percent of the historians rated Bush's presidency in last place. Among the reasons given for his low ratings: invading Iraq, "tax breaks for the rich," and alienating many nations around the world. Bush supporters counter that professional historians today tend to be liberal and that it's too early to assess how his policies will turn out.
