Top FEMA officials are Bush's incompetant pals

So you all heard the Mike Brown is out as FEMA director, due to his inability to, uh...do anything. But the problem is not limited to him:

Five of eight top Federal Emergency Management Agency officials came to their posts with virtually no experience in handling disasters and now lead an agency whose ranks of seasoned crisis managers have thinned dramatically since the Sept. 11, 2001, attacks.

FEMA's top three leaders -- Director Michael D. Brown, Chief of Staff Patrick J. Rhode and Deputy Chief of Staff Brooks D. Altshuler -- arrived with ties to President Bush's 2000 campaign or to the White House advance operation, according to the agency. Two other senior operational jobs are filled by a former Republican lieutenant governor of Nebraska and a U.S. Chamber of Commerce official who was once a political operative.

Reading the last part of the first paragraph, I wonder, WHY are FEMA officials with experience leaving? Is it they can't handle a crisis, or that their hands are so tied to a sinking ship that they had no choice?
