Rudy Giuliani is not a hero.
In fact, even The New York Times today is a little surprised that Giuliani is so scared on the campaign trail that he handpicks who gets to come see him. On the stump? Yes. Off the cuff real questions? No chance.
Could it be he doesn't want anyone asking about why he shipped Bernard Kerik out of the country or about his marriage to his cousin or his decision to put the New York City Command and Control Center next to the World Trade Center against the wishes of the FBI?
Could also be he's just a coward. Nothing more. Maybe less.
