About burrowing by the Bush appointees at the head of the Civil Service-the fact is that they would be easier to get rid of than lower levels. They are management without union protection (not that the unions want these types in them), and they can be gotten rid of. Given the quality of Bush hires, they are mostly incompetent, poorly trained, and probably obstructionist to boot, which will make them perform poorly. My impression too is that they think the wingnut welfare machine will protect them even if they openly sabotage Obama. I don't think these Regent Graduates are bright enough to realize that the right-wing money machine has several problems at once:
1) Investments. Several money angels have gone from billionaires to millionaires due to bad investments. Those who remain are aging and will soon be replaced by heirs who would rather party it up than support right-wing madness. The absence of the usual right-wing sugar daddies this election cycle was noticable. The people who funded Linda Tripp et al, aren't going to go out of their way this time.
2) Obama may reinsource a lot of the contracted out work-he has a reason to do so: economy. Federal Employees want a decent salary, but nobody is going to get a million dollar salary working for the Feds, nor do they require profit margins. Blackwater and other such boondoggles are a luxury America can no longer afford.
With the breakup of so many good companies, and the general economic environment, the Obama heads of agencies will be able to pick up superior talent pretty quickly from the private sector, which will even further limit these burrowers options further. Burrowers will either have to become honest employees or quit.
