Bloomberg left the GOP party Tuesday.

WASHINGTON (CNN) — A day after quitting the Republican Party to become an independent politician, New York City Mayor Michael Bloomberg brushed aside speculation that he’s going to run for president on a third party ticket. But he wouldn't close the door completely.

"I have said that my intention is to be mayor for the next 925 days and probably about 10 hours, whatever's left, 11 hours," Bloomberg said during a news conference in New York City. "And that is my intention. I've got the greatest job in the world and I'm going to keep doing it."

But the New York City mayor also noted, "The more people that run for office the better."

Bloomberg said he dropped his Republican Party affiliation, because he wanted to be able to speak out about issues like immigration, Iraq and health care more effectively. The mayor said he thinks there are already a lot of choices for presidential candidates and that attention should be spent on those that are actually running.

"I think they're wasting they're time, I'm not a candidate, they should get down to polling on people who are candidates and we've got a lot of them in this country," he said. "We even have two people from New York who are candidates for President of the United States, I'm not sure the state needs a third."

He has made similar comments in the past.

But what would it take for Bloomberg to run?

"If everyone in the world was dead and I was the only one alive, sure," Bloomberg joked.
