Bloomberg reports that Timothy Geithner is trying to push out Sheila Bair, head of the FDIC. Bair has gotten a lot of good press in recent months for her aggressive focus on helping individual homeowners, and she was often mentioned in the same breath as Geithner for the Secretary of the Treasury position, largely because folks thought they had proven themselves fairly similar during the crisis: Pragmatic moderates who'd been radicalized by the moment and were willing to accept that the rules had decisively changed. I'd figured that would make them natural allies, but maybe not.
