Democratic gubernatorial candidates Neil Abercrombie and Mufi Hannemann will face off again in a live debate tomorrow as they enter the final three weeks of their primary election battle.

The debate, from 6:30 to 8 p.m. at the Blaisdell Center’s Pikake Room, is sponsored by the Honolulu Star-Advertiser and Hawaii News Now.

The debate will be broadcast on KHNL, KGMB and KFVE, and will re-broadcast Sept. 4 at 6:30 p.m. on KHNL and KGMB.

Keahi Tucker and Tannya Joaquin will moderate. Star-Advertiser political columnist Richard Borreca, MidWeek political columnist Dan Boylan, Hawaii News Now reporter Teri Okita and former KGMB anchorwoman Kim Gennaula will serve as panelists.

The Star-Advertiser and Hawaii News Now will live-stream the debate on their websites.

A poll of likely voters conducted Aug. 10-17 by Ward Research for the Star-Advertiser and Hawaii News Now showed essentially a dead heat between former Congressman Abercrombie and former Honolulu Mayor Hannemann, with Abercrombie slightly ahead.

The primary election will be held Sept. 18.
