WASHINGTON — Popular New York Mayor Michael Bloomberg on Sunday insisted he has no intention of running for president in 2012.

"I'm not looking at the possibility of running. I've got a great job and I'm going to stay with it. I am going to speak out on those things that affect New York City. That's my job," he told NBC's "Meet the Press."

When pressed if he would consider running were his advisers to tell him he had a strong chance of winning, Bloomberg replied: "No way, no how."

The 68-year-old billionaire is a political independent but ran as a Republican, and was re-elected to a third term as mayor in 2009.

Since he first assumed office in 2001, Bloomberg has been widely credited with advancing the evolution of once gritty and chaotic New York into one of the cleanest, safest and most efficient US cities.

He has overseen a surge in luxury developments, barred traffic from teeming Times Square, made restaurants display calorie counts and banned smoking in bars, with a view to extending the ban to city parks.

The founder of Bloomberg LP, an international news and financial data giant, is one of the top ten wealthiest Americans, with a fortune estimated at around 18 billion dollars, according to Forbes magazine.
