First Aide?

McCain aide Charlie Black's quote from Fortune:
"The assassination of Benazir Bhutto in December was an "unfortunate event," says Black. "But his knowledge and ability to talk about it reemphasized that this is the guy who's ready to be Commander-in-Chief. And it helped us." As would, Black concedes with startling candor after we raise the issue, another terrorist attack on U.S. soil. "Certainly it would be a big advantage to him," says Black."

As the AP points out, McCain himself used the Bhutto assassination to boost his own candidacy:
"My theme has been throughout this campaign that I'm the one with the experience, the knowledge and the judgment. So perhaps it may serve to enhance those credentials to make people understand that I've been to Pakistan, I know (President Pervez) Musharraf, I can pick up the phone and call him. I knew Benazir Bhutto."
