WE like our failed presidents to be Shakespearean, or at least large enough to inspire Oscar-worthy performances from magnificent tragedians like Frank Langella. So here, too, George W. Bush has let us down. Even the banality of evil is too grandiose a concept for 43. He is not a memorable villain so much as a sometimes affable second banana whom Josh Brolin and Will Ferrell can nail without breaking a sweat. He’s the reckless Yalie Tom Buchanan, not Gatsby. He is smaller than life.

The last NBC News/Wall Street Journal poll on Bush’s presidency found that 79 percent of Americans will not miss him after he leaves the White House. He is being forgotten already, even if he’s not yet gone. You start to pity him until you remember how vast the wreckage is. It stretches from the Middle East to Wall Street to Main Street and even into the heavens, which have been a safe haven for toxins under his passive stewardship. The discrepancy between the grandeur of the failure and the stature of the man is a puzzlement. We are still trying to compute it.

The one indisputable talent of his White House was its ability to create and sell propaganda both to the public and the press. Now that bag of tricks is empty as well. Bush’s first and last photo-ops in Iraq could serve as bookends to his entire tenure. On Thanksgiving weekend 2003, even as the Iraqi insurgency was spiraling, his secret trip to the war zone was a P.R. slam-dunk. The photo of the beaming commander in chief bearing a supersized decorative turkey for the troops was designed to make every front page and newscast in the country, and it did. Five years later, in what was intended as a farewell victory lap to show off Iraq’s improved post-surge security, Bush was reduced to ducking shoes.

He tried to spin the ruckus as another victory for his administration’s program of democracy promotion. “That’s what people do in a free society,” he said. He had made the same claim three years ago after the Palestinian elections, championed by his “freedom agenda” (and almost $500 million of American aid), led to a landslide victory for Hamas. “There is something healthy about a system that does that,” Bush observed at the time, as he congratulated Palestinian voters for rejecting “the old guard.”
