What's really being satirized here is sexual advice columnists. What's really being implicitly praised is Rumsfeld's style of no-nonsense straight talk and how it would apply to the wishy-washy world of sexual advice.
Rumsfeld isn't being mocked in this piece at all, which is why nobody here is complaining.
A similar piece with questions for Clinton wouldn't work because Clinton speaks in the same mushy way that most advice columnists write (not to mention all the ironies given Clinton's deviancy). You might get a chuckle out of "it all depends on what the meaning of 'orgasm' is", but not much of a laugh.
