Zelda Bronstein, who writes the “Public Eye” column on local issues for the Berkeley Daily Planet, is stepping down in order to run for mayor of Berkeley, according to a column by Becky O’Malley, part-owner of the twice-a-week paper. “In her place, we’re asking other people who are involved in local politics in the East Bay to try their hand at writing Public Eye columns,” O’Malley writes. “Anyone who is both a good writer and a participant in the action is welcome to try out for this slot.” Previously Bronstein was chair of Berkeley’s Planning Commission. Owner O’Malley used to sit on the city’s Landmarks Preservation Commission.
