This is exactly what Krauthammer predicted would happen, interestingly enough. (Rf. Saving Face by Charles Krauthammer).
Bush, after weeks of insisting he did not want Miers to withdraw, blamed the Senate for her demise.
"It is clear that senators would not be satisfied until they gained access to internal documents concerning advice provided during her tenure at the White House _ disclosures that would undermine a president's ability to receive candid counsel," the president said shortly before leaving for Florida to assess hurricane damage.
Finally, light at the end of this tunnel. A way out: irreconcilable differences over documents.
For a nominee who, unlike John Roberts, has practically no previous record on constitutional issues, such documentation is essential for the Senate to judge her thinking and legal acumen. But there is no way that any president would release this kind of information -- ``policy documents'' and ``legal analysis'' -- from such a close confidante. It would forever undermine the ability of any president to get unguarded advice.
Which creates a classic conflict, not of personality, not of competence, not of ideology, but of simple constitutional prerogatives: The Senate cannot confirm her unless it has this information. And the White House cannot allow release of this information lest it jeopardize executive privilege.
Hence the perfectly honorable way to solve the conundrum: Miers withdraws out of respect for both the Senate and the executive's prerogatives, the Senate expresses appreciation for this gracious acknowledgment of its needs and responsibilities, and the White House accepts her decision with the deepest regret and with gratitude for Miers' putting preservation of executive prerogative above personal ambition.
