In the Barack Obama version, there are 50 or so such blame-Bush free passes before the gig is up. By my calculation, Obama has already burned through a good 49. Is there anything he hasn’t blamed George W. Bush for? The economy, global warming, the credit crisis, Middle East stalemate, the deficit, anti-Americanism abroad — everything but swine flu.

It’s as if Obama’s presidency hasn’t really started. He’s still taking inventory of the Bush years. Just this Monday, he referred to “long years of drift” in Afghanistan in order to, I suppose, explain away his own, well, yearlong drift on Afghanistan.

This compulsion to attack his predecessor is as stale as it is unseemly.
