Well, John McCain's judgement has now been tested. And he's failed that test spectacularly. The most important test of anyone who runs for president is the ability to choose first a running mate, then an administration. On the occasion of his 72nd birthday, in front of a banner that, without irony, read "Country First," McCain chose Alaska Governor Sarah Palin, a hard right-winger who is plainly not ready to step-up in the event of McCain's inability to serve out his term.
