Why has the Bush cabinet been unstable?
Well, I’m not sure it is necessarily more unstable than other presidental administrations—you’d have to check that out in more detail to make that claim. But some of the resignations have been due to scandals, lawsuits, or failures, from what I can tell, though with others it is harder to say that with much confidence, unless there are complicated internal politics that I am not privy to, which is likely.
