According to The Telegraph, the longhaired, tattooed Burck has become a Times Square feature and plans to make an official announcement on his web site www.nakedcowboy.com.
"No one knows how to do more with less than yours truly, and that's the kind of thinking I plan on sharing with my fellow New Yorkers when you elect me," said Burck, announcing his bid to run against Mayor Michael Bloomberg.
Burck earns about 1,000 dollars a day with his busking.
Bloomberg, a billionaire, intends to run for re-election as mayor hoping for a third four-year-term.
He has already spent millions of dollars on his campaign, including on a blizzard of television commercials, while his only real challenger, the little-known city comptroller, William Thompson, has struggled to be heard.
