From The New York Times...

Perhaps Bloomberg said it in jest. If not, it certainly throws an interesting angle into Christine Quinn's presumed candidacy.

UPDATE: Here's the story.

During their conversation, Mrs. Clinton left little room for doubt: she was not interested in seeking the mayoralty, people briefed on the call said. Even so, Mr. Bloomberg’s reaching out to her is rich with political intrigue. He has privately signaled support for the presumptive candidacy of Christine C. Quinn, the City Council speaker, who cleared a path for his third term by backing a change to the city’s term-limit law. The mayor’s political apparatus has begun to coalesce around Ms. Quinn, and she promotes herself as a leader who ran the city alongside Mr. Bloomberg. In many corners of the city’s political world, Mr. Bloomberg’s eventual endorsement of Ms. Quinn has been considered a foregone conclusion, barring the entry of a big-name candidate into the field. But the mayor’s conversation with Mrs. Clinton, even after he had begun to telegraph his allegiance to Ms. Quinn, suggests that, to a degree previously unknown, his thinking has been unsettled.

The Times asked Quinn about the call: "Really? I don’t know anything about that."
