San Franciscans regularly vote on so many ballot measures that their pamphlets feel like phone books. ADVERTISEMENTLurie’s team will share his stances with a 30-plus-member charter reform task force on Friday, sources with knowledge of the mayor’s plans told The Standard. The working group was convened by Lurie and Board President Rafael Mandelman in December, with the goal of producing a range of recommendations on streamlining governance. Union representatives on the charter reform group have voiced objections to making it tougher to place measures on the ballot. “The city charter fosters a culture of corruption and protects the status quo at the expense of San Franciscans,” he said.
