David Broder savages his Washington Post colleagues in this remarkable column on whether President Obama has screwed up by not following his chief of staff's advice. Writes Mr. Broder off the leaks from allies of Rahm Emanuel: "the chief of staff doesn't usually force the president out. When George H.W. Bush had had enough of John H. Sununu, of course it was Sununu who walked. Maybe the sources on these stories think Obama is the one who should leave."
