Supporters of Measure E, San Diego’s proposed one-cent sales tax hike, have raised more than $1 million from city labor unions and other groups to help mount a strong campaign in favor of the ballot measure. Opponents of Measure E, a group being led by the San Diego County Taxpayers Association, have raised significantly less — $45,000. Two other city ballot propositions, Measures C and D, have not generated any fundraising for or against. Measure C would would reform board elections in the San Diego Unified School District, and Measure D would give the city’s Ethics Commission more power. In the battle to succeed City Attorney Mara Elliott, Deputy City Attorney Heather Ferbert continues to out-raise runoff opponent Assemblymember Brian Maienschein. Disclosures released Thursday covering July 1 through Sept. 21 show Ferbert raised 10 times as much as Maienschein, $17,000 versus $1,700. But as the candidates head into the homestretch for the Nov. 5 election, Maienschein has more cash on hand, $137,000 compared to $110,000 for Ferbert. In the runoff for mayor, incumbent Todd Gloria out-raised challenger Larry Turner $104,000 to $70,000 between July 1 and Sept. 21. Gloria has $366,000 in cash on hand, while Turner has only $23,000. But a $1 million donation to the political arm of the Lincoln Club of San Diego County might help pay for mailers, ads and other efforts to help Turner beat Gloria. A Lincoln Club official said the money may be used to help Turner, but the leader of the club’s political action committee said Thursday that no decisions had yet been made on how to spend it. In City Council runoffs, incumbents continue to lead in fundraising. In District 3, incumbent Stephen Whitburn raised $15,000 during the reporting period, nearly twice as much as challenger Coleen Cusack at $8,000. Heading into the campaign’s final stretch, Whitburn has $76,000, and Cusack has just $3,400. In District 9, incumbent Sean Elo-Rivera raised $10,000 during the reporting period, and challenger Terry Hoskins raised $8,000. Elo-Rivera has $32,000 cash on hand, while Hoskins has $12,000. On Measure E, the bulk of the $1 million raised by supporters has come from city labor unions: $500,000 from the Municipal Employees Association, which represents white-collar workers; $130,000 from the firefighters labor union; $60,000 from the police officers union; and $5,000 from the union that represents blue-collar workers. Other large contributions include $40,000 from the Balboa Park Cultural Partnership, $35,000 from the Sycuan Band of the Kumeyaay Nation, $30,000 from Affirmed Housing and $10,000 each from Falck USA ambulance service and the local chapter of the Building Industry Association. Supporters have spent $122,000 on posters and election consultants, leaving them nearly $900,000 for the rest of the campaign. The opposition campaign to Measure E is being funded so far by three organizations. Diamond Environmental Services, which specializes in portable toilets, has contributed $25,000. The campaign has also received $10,000 each from the San Diego Restaurant and Beverage Political Action Committee and the New Car Dealers Association. Opponents have already spent $15,000 on digital ads.
