The Worst President in History?

Was the lousiest James Buchanan, who, confronted with Southern secession in 1860, dithered to a degree that, as his most recent biographer has said, probably amounted to disloyalty -- and who handed to his successor, Abraham Lincoln, a nation already torn asunder? Was it Lincoln's successor, Andrew Johnson, who actively sided with former Confederates and undermined Reconstruction? What about the amiably incompetent Warren G. Harding, whose administration was fabulously corrupt? Or, though he has his defenders, Herbert Hoover, who tried some reforms but remained imprisoned in his own outmoded individualist ethic and collapsed under the weight of the stock-market crash of 1929 and the Depression's onset? The younger historians always put in a word for Richard M. Nixon, the only American president forced to resign from office.
Now, though, George W. Bush is in serious contention for the title of worst ever. In early 2004, an informal survey of 415 historians conducted by the nonpartisan History News Network found that eighty-one percent considered the Bush administration a "failure." Among those who called Bush a success, many gave the president high marks only for his ability to mobilize public support and get Congress to go along with what one historian called the administration's "pursuit of disastrous policies."
