After claiming not to have his mind made up before taking to the airwaves for his afternoon talk show, 73-year-old Vincent A. "Buddy" Cianci Jr. revealed Wednesday he's staging an improbable comeback to become the next mayor of Providence.

Cianci is running as an independent -- the same approach he used during his 1990 return to power  -- in a close three-way race, after having first won office in 1974 as a Republican.
