Three candidates for the City Council seat left vacant by the death of Councilman Duke Bainum filed for office yesterday.

Former Councilwoman Ann Kobayashi said she would also run in the special election that will be conducted by mail, with the results announced on Aug. 7. Candidates have until June 25 to file with the city clerk.

Kobayashi, in a statement issued while she is traveling in Europe, said her supporters persuaded her to run again.

Last year, Kobayashi unsuccessfully ran for mayor instead of running for re-election. Former Councilman Duke Bainum ran for her Manoa, Palolo and Kapahulu district seat and won.

Yesterday, George Waialeale, Greg Cuadra and Robert Whitaker filed. Waialeale and Cuadra have served as Moiliili-McCully Neighborhood Board members, and Waialeale is a former union official.
