About this endorsement list
This is the Yes on 40 campaign’s list for California Proposition 40 (2026), the California Billionaire Tax Act. Its original names and entity records are retained; additional research supplies the quotations, media and source links shown here. A quote from a union or organization’s spokesperson is attributed to that speaker, without automatically adding another individual endorsement.
Names, organizations, quoted statements and sources are connected in the page’s structured data as well as in the readable text. An identity link tells you who an endorser is; it is not treated as proof of support. A news publisher’s coverage, a government office’s voter guide and a parent institution’s affiliation do not create additional endorsements.
Roster snapshot: . Additional sources reviewed: . Quotes were checked against the linked written sources; video titles and descriptions were located, but uninterrupted playback and third-party embedding permissions were not independently tested.
