Everyone be prepared for the admin to say that, while technically they may have not said things as "fully" as the politically-motivated GOP wants, but that nothing illegal happened and it wasn't their intent to mislead. And that they will get to the bottom of it. And that it is Bush's fault. And that the GOP is getting in the way of the people's business.
Also, the media will move on from this and claim the GOP is "overplaying" any misdeeds.
You saw it happen with Jay Carney who can't bring himself to admit he lied and the IRS commissioner today saying he told the truth. No one outside of the right will call them on it and Obama will eventually turn this into a marginalized, partisan witch hunt.
