As someone willing to vote for Giuliani in the general election, I think he is a goner (assuming this report is true).
I read it, and I'm still wondering what the story is. It seems that the Mayor's security detail is paid for by the city, and includes security costs for his personal trips and travel. Well... of course it does. Security details are all of the time, not just working hours.
Somebody want to tell me what the big deal is?
