Meanwhile, Andy Card is being blamed for the Harriet Miers nomination:

One of Miers' jobs as White House counsel was to judge the judges, including the search that ended with the Roberts pick. According to a presidential adviser who has been briefed on the chronology of the decision, senior adviser Karl Rove was less involved than he is in most major decisions. Some conservatives speculate that Rove was distracted or out of the loop because of his possible legal jeopardy in the CIA leak case, but White House officials reject that notion.

The driving force was chief of staff Andrew H. Card Jr., who took over the vetting role. "This is something that Andy and the President cooked up," the adviser told TIME. "Andy knew it would appeal to the President because he loves appointing his own people and being supersecret and stealthy about it." Relations between Rove and Card have always been strained, and this adviser said the nomination has reignited the tension. Another Republican involved said it reflected Bush's isolation. "Somebody just like her should have told him, 'Mr. President, no. This is a mistake.' But he picked the picker, so there was no one there to tell him no."
