THE BURNED OVER DISTRICT

It is hard to say if he achieved what he wanted after 12 years as mayor but, thanks to the diligence of the New York Times we have a good idea how much he paid out of his own pocket for the privilege.

When Mr. Bloomberg leaves office at midnight Tuesday, he will bequeath a litany of record-shattering statistics on crime reduction, sidewalk safety and skyline-altering construction. But perhaps the most staggering figure is the amount of his own money that he devoted, day in and day out, to being mayor — much of it unseen by the public.

An analysis by The New York Times shows that Mr. Bloomberg has doled out at least $650 million on a wide variety of perks and bonuses, political campaigns and advocacy work, charitable giving and social causes, not to mention travel and lodging, connected to his time and role as mayor. (His estimated tab for a multiday trip to China, with aides and security in tow: $500,000.)

In the process, he has entirely upended the financial dynamics surrounding New York’s top job.

In the past, the city paid its mayor; Mr. Bloomberg paid to be the city’s mayor.

In moves that would make a financial planner’s head spin, he rejected the $2.7 million worth of salary to which he was entitled (accepting just $1 a year) and, starting in 2001, turned on a spigot of cash that has never stopped gushing. He poured at least $268 million of his personal funds into three campaigns for mayor.

He donated at least another $263 million to New York arts, civic, health and cultural groups, personally and through his company, Bloomberg LP.

Campaign donations? He handed out about $23 million of them.

He even chipped in $5 million to renovate an official mayoral residence that he never inhabited. (He preferred the familiar privacy of his own nearby mansion.)

“A modern Medici” is how Mark Green, the former public advocate, described him, reaching back to 15th-century Italy for any kind of precedent.

Mr. Bloomberg’s all-expense-paid mayoralty was, depending on the vantage point, exhilarating (for his aides), infuriating (for his rivals) cost-saving (for his constituents) or selfless (for the beneficiaries of his largess).

And the $650MM is a low estimate. What a strange little man.
