Judgments behind this record
Verdict on the claim
Call: Supported
The FPPC list shows Building a Better California, whose top donors it lists as Sergey Brin and L. John Doerr III, gave $89,800,000 to the Proposition 42 committee and $58,350,000 to the Proposition 41 committee. Cal-Access itemized filings for Building a Better California list seven contributions from Sergey Brin between January 12 and July 24, 2026, totaling $102,000,000, more than the $57 million the argument cites. The filings do not trace his money measure by measure. "Sham" is a characterization, not a checkable fact.

Copy the public log and run its script. It reads only the public log: the signed copy of this record, the judgments behind it, the keys and the receipts. It recomputes each fingerprint and checks the proof, both signatures and the timestamps. It checks the signed copy in the log, not the text on this page:
git clone https://github.com/Macpire/ideology-integrity-log
cd ideology-integrity-log
npx tsx integrity/verify-record.ts --log ca-2026 ca-prop-42-claim-5 --repo .To check that the text this site serves is that signed copy, add the site's address. Only this check ties the log to what you read here:
