Jon Stewart Is Out of the Will

The deterioration of John McCain can be measured by the arc of his appearances on "The Daily Show" with Jon Stewart.

As Stewart's most frequent guest, McCain started out as the feisty older brother who could make us laugh at the foibles of our elders, but he has gone downhill ever since until he is now the embarrassing uncle who keeps saying inappropriate things and just won't shut up.

Jon Stewart, to his credit always respectful of elders, last night finally stop deferring to McCain and tried to sober him up on the subject of Iraq. There will be a chill in the air at future gatherings, if any.
