Misplaced Confidence

But that should not obscure two fundamental points: First, the president’s apparently unshakable confidence in his attorney general is sadly misplaced. Second, the disturbing behavior uncovered in the investigation of the firing of U.S. attorneys cannot be dismissed as mere partisan politics, as much as the president would like to do so. Partisan politics was at work, yes, but in Mr. Bush’s Justice Department — in the hiring of career lawyers and the selection of immigration judges — and, with the involvement of the White House, in the ouster of at least some of the prosecutors.
