John McCain answered Bill Clinton’s assessment of the mental stability of POWs today on Fox News.  He delivers what may be the classic rebuttal of his career, exposing Clinton’s lack of standing to even comment on such an issue:

McCain shrugs off the attack, answering that the Obama campaign can say whatever it wants about his military experience, but one has to wonder why the Democrats keep raising the issue. It only gives McCain an opportunity to speak about his war service, his love of country, and to remind voters that neither Bill Clinton nor Barack Obama served at all. They continually play to his strength while highlighting Obama’s weakness on military affairs.

And in this case, they get to highlight McCain’s sense of humor. Almost as good as the zinger is the gale of laughter that precedes it.
