If Miers is not up to it–the hearings and the Court–and the White House knows that, there seems no excuse, political or otherwise for her name to not be withdrawn immediately. Embarrassing for the White House? Sure. But a short-term mistake fixed sooner rather than after an added disaster in the Senate would be the better in the long run–nevermind better than the long-term mistake of appointing someone not up to snuff to the Court (how do I know she isn’t? I don’t. But I’m working with the White House’s inability to make the case for her).
