Nir Zilberman, owner of LA Jock, has cancelled a proposed debate at his store on Sunday among candidates in the March 5 election for West Hollywood City Council. Zilberman cancelled because few candidates agreed to appear. To date, there have been three debates among candidates for the two council seats. One held last month by a group of neighborhood associations attracted all nine contenders. Two others — one at West Hollywood College Preparatory School and another staged by the Apartment Association of Greater Los Angeles — were only attended by challengers. The West Hollywood Chamber of Commerce, which traditionally hosts a council candidate debate, has not done so this year.
