A nonprofit pushing for bolstered child care access, local health care organizations, labor unions and two wealthy San Diegans are fueling the Measure B campaign.
Measure B is a proposed countywide half-cent sales tax that would fund health care, child care, Tijuana River sewage solutions, public safety and food benefits.
Here’s a breakdown of the major funders of the campaign, which has reported pulling in more than $3.4 million through Oct. 28.

Children First San Diego – $670,000
This 501(c)4 nonprofit is focused on increasing child care options, supporting providers and child development. The nonprofit’s primary funder is the Bay Area-based Heising-Simons Action Fund.

Longtime San Diego power player Mel Katz chairs the San Diego Foundation. Early this year, Katz gave the Yes on B committee two loans totaling $500,000. Separate from those loans, he and his staffing company Manpower have also donated $79,252 to the committee. Katz is also a donor to Voice of San Diego.
