Mayor Bloomberg had a different answer yesterday for that same old question he’s dismissed over and over: Are you going to run for president?

“I don’t think so — and if I was going to do it, I don’t think I’d announce it right here,” he said during a brief appearance yesterday morning on Fox News.

A host noted that the billionaire businessman had a similar answer when asked, years ago, if he planned to run for mayor.

“And then fast forward, here you are,” she said.

“You never know,” he told her.

For the record, just days ago Mr. Bloomberg told an audience at Harvard University that he was not, in fact, a presidential candidate.

Ever since the Democrat-turned-Republican won re-election in 2005 — stomping his opponent in this left-leaning town —there have been murmurs of Mr. Bloomberg’s presidential aspirations. Most are fueled by one of his aides, Kevin Sheekey, who has publicly acknowledged his efforts to cajole his boss into the race.

The scenario floated by Mr. Sheekey and other supporters has Mr. Bloomberg waiting until next year, when the front-runners for both parties are clear.

If one candidate is way on the left and the other far to the right, some envision room for Mr. Bloomberg right down the middle as an independent.
