Harold Meyerson nails Bush to the wall
How could a president get these things so wrong? Incompetence may describe this presidency, but it doesn't explain it. For that, historians may need to turn to the seven deadly sins: to greed, in understanding why Bush entrusted his new drug entitlement to a financial mainstay of modern Republicanism. To sloth, in understanding why Incurious George has repeatedly ignored the work of experts whose advice runs counter to his desires.
Personally, I think the silver lining of Bush's presidency is that he's broken the glass ceiling that was holding down the mentally challenged.
