From the Financial Times:
The Bush administration is facing growing difficulties in filling a rising number of high-level vacancies following a recent spate of senior departures.One doesn't need to be a genius to figure out why people might be a little leery of joining the most unpopular administration in a generation.
In the last 10 days alone Mr Bush has lost four senior officials and more resignations are expected to follow. "I wouldn't describe this as disintegration," said one senior official. "But there are worrying large gaps opening up and it is very hard to recruit high-quality people from outside."
Ignoring the fact that Bush is staggeringly unpopular, why would you decide to take some job for the Bush Administration? Dick Cheney is going to make all the decisions anyway...
