Hmm.

Like everybody else, I've been caught up in the John Adams hoopla thanks to the HBO joint. I just started wondering what, as sons of ex-presidents, do John Quincy and Dubya have in common? A quick trip to Wikipedia found this sentence:

Much of Adams' political difficulties were due to his refusal, on principle, to replace members of his administration who supported Jackson (on the grounds that no one should be removed from office except for incompetence.)

and, sensing futility, I quickly gave up my search.
