Some of the calls for a White House shake-up are now coming from inside the building.

Frustrated current and former West Wing staffers, speaking on condition of anonymity, told POLITICO they hoped Tuesday night�s humbling losses would convince President Barack Obama to pursue a much more sweeping fix than just the �natural� post-election churn of personnel his administration has insisted will take place.

Many of those changes are already being seriously considered, among them replacing political director Patrick Gaspard with a former top aide to Rahm Emanuel; replacing Deputy Chief of Staff Jim Messina, who is expected to move to Obama�s 2012 campaign, with legislative affairs director Phil Schiliro; and possibly giving White House energy czar Carol Browner more expanded policy responsibilities.

But if Obama�s critics are focusing on his agenda and messaging, many on his own team are urging him to address what they see as a major organizational flaw: an amorphous, ill-defined chain-of-command in the West Wing that concentrates too much power in too few hands, hampering efficiency, accountability and communication.
