Bill Kristol wants some of the young bucks to get out of the game before they hurt themselves:
Is John McCain the best messenger for his campaign? Why isn’t he on this show? Why do we have Tucker Bounds and a bunch of nice young kids who are spokesmen out there spinning implausibly on behalf of the McCain campaign? McCain is better than his campaign.
Kristol doesn't mind agitating for wars of choice in which "nice young kids" will fight and die, but to have them out here "spinning implausibly," well that's just ... that's just low.
