June 2026 Impact Report

How we held our majorities

Impact report hero

Over the last 18 months, the city has made real progress on public safety, housing, education, and our economic recovery. June 2026 wasn't about new gains — it was about not losing what we'd built.

Two critical Supervisor seats and a Board of Education seat were on the ballot, along with Proposition D, a new tax on grocery stores and pharmacies that would have driven up costs for everyday San Franciscans.

Our approach: run early candidate campaigns across every channel to build name recognition before voters tuned in, then deploy our trusted voter guide so every voter knew who we supported and opposed.

Results

Every candidate GrowSF supported in June won. These wins kept our commonsense majorities on both the Board of Supervisors and the Board of Education intact — the majorities San Francisco needs to keep making progress on public safety, housing, and schools.

Voters also rejected Prop D, a new tax on grocery stores and pharmacies that would have driven up costs for everyday San Franciscans. We commissioned an independent study of its real impact, brought those findings to voters, and helped defeat it.

Our opponents weren't honest about what was on the ballot. They sold Prop D as a “CEO tax,” but it was really a tax on groceries and pharmacies. We stuck to what we do best: a voter guide that sources every claim and lets voters decide for themselves.

What's Next

November 2026 is the biggest ballot in years.

November is the most consequential San Francisco ballot in years, and we're running a full operation to win it.

Voters will decide five supervisor seats, three school board seats, charter reforms to cut the red tape and fix how City Hall manages its budget, and critical funding that determines whether Muni keeps buses running and expands service.

We've proven we can move votes at scale by being a trusted source on the candidates and policies that make San Francisco safer and more affordable. With your support, we'll win big in November and lock in reforms that help San Francisco for decades.
