Bloomberg, speaking Friday on New York's WABC radio, said that if the stadium has not been approved by the June 6 IOC evaluations, "London and Paris will use that as they go around for the next month, every day banging on every one of those 115, 116 [IOC] delegates, saying, 'You see, you see, you see, they're not behind it.' "
On the other hand, approvals could send New York to Singapore with what bid leader and deputy mayor Dan Doctoroff called "incredible momentum."
The 75,000-seat stadium, which would be built by the Jets on a 13-acre platform over an operating rail yard, would cost about $2 billion, according to the most recent estimates. The city and the state would each put up $300 million.
If the stadium were built, the NFL already has announced the 2010 Super Bowl would be played there.
The key selling point for Bloomberg is not football or the Olympics. The sports connections, he has maintained over and again, serve as a catalyst for the redevelopment of the far West Side, centered on the stadium as an expansion of New York's undersized convention center.
The opposition has been fierce, driven in part by an advertising campaign on local television underwritten by Cablevision -- which owns Madison Square Garden and had submitted a rival bid for the rail yard.
Opponents have maintained that the stadium proposal is the wrong idea for West Side development, that it is too expensive, or would not prove economically feasible -- even bemoaning the lack of space for tailgating before Jets' games.
New York Gov. George E. Pataki, state Senate Majority Leader Joseph Bruno and Silver, the assembly speaker, control the Public Authorities Control Board; that panel has jurisdiction over the state borrowing necessary to finance the stadium. The panel's three voting members must be unanimous for a project to win approval. The board vote has been delayed twice.
Bloomberg is up for reelection in the fall. "It's a matter of horse trading and white-knuckle negotiation," said George Arzt, a veteran New York political consultant, adding, "I don't think Shelly [Silver] or Bruno want to be the people who lose the Olympics, or have newspaper headlines, 'They cost us the Olympics.' That's one of the things in the mayor's favor."
Last September at the Jets' opener, Bloomberg turned the pressure on -- on himself, perhaps more than anyone.
"You're talking about a guy who believes in the ultimate spirit of can do-ism," said Hank Sheinkopf, another longtime New York political consultant. And "he was confident he would win the battle."
