Huh:

White House Chief of Staff Andrew H. Card Jr. is unhappy because too many top Bush aides are hanging on to their jobs -- even though he's encouraging them to take a hike.

"I've expressed that frustration to the senior staff," he told the New York Times on Monday. He said he had been "surprised" more hadn't quit, noting that President Bush wanted to "have more energy."

I have no idea what to make of it.
