From a reader:

You don’t know the half of it.
The Bush/Rove cabal scheduled the soft retirement of O’Connor prior to the demise of Rehnquist (someone is looking into this, I assume), allowing for Roberts to leapfrog to Chief Justice while the Fitzgerald Grand Jury prepared for indictments so Miers was set up to be knocked down the day before thus hiding the Rove/Libby outing of the already oft outted CIA agent, Plame.
So simple, really.
