From NYTimes on Andy Card:

“The lesson of both Katrina and Miers is that the system of decision making in the White House no longer meets the needs of the president,” said David Frum, a former speechwriter for Mr. Bush who has been critical of the Miers choice.

Even if you think Bush got unfair press–on the left and right–there was a tone-deafness that just can’t be in an effective White House. And that’s even before we got to the Michael Brown p.r. disaster.
