On the ballot

This person holds your district's seat in the California State Assembly (2-year term).

Assemblymember Catherine Stefani took 83.0% of the June 2 vote and Republican Philip Louis Wing took 17.0%; they were the only two candidates on the primary ballot. The district covers western San Francisco.

The winner holds one of 80 Assembly seats for a two-year term, inside a 12-year lifetime cap on service in Sacramento. An Assemblymember authors bills, sits on the policy committees that decide which bills advance, and argues for the district's share of the annual state budget. A first-term member is still building the committee position that determines how much of that agenda actually moves.

This is a two-candidate race with a wide June margin and a marked difference in how much each candidate has made public. One has a first-session legislative record and a fully funded campaign; the other declined a local voter-guide questionnaire and has no reported fundraising. Weigh the incumbent's record on its own terms, and weigh how much you are prepared to decide about an opponent who has published little.

Catherine Stefani

Democrat, the sitting Assemblymember for this district and a San Francisco supervisor before her election. She is lead author of 35 bills in the 2025–2026 session, 7 of them signed into law. She took more than eight in ten votes in the June primary.

Strengths

Thirty-five bills authored and 7 signed into law in a first session, on top of years in city government covering the same neighborhoods.

Trade-offs

Her funding sits close to the ballot median and nothing adverse surfaced in her first-session record; the trade here is continuity rather than change.

Keep in mind

One session is a short legislative record to judge, however active.

Philip Louis Wing

Republican, and the only other candidate on this district's ballot, with 17.0% of the June vote. He has been registered with a Republican party preference in San Francisco since 2016. He has not served in the California Legislature or U.S. Congress.

Strengths

He gave this district a contested race rather than an unopposed one, and took roughly one vote in six doing it.

Trade-offs

Cal-Access shows no contributions reported for his committee, and he has no record in office to be judged on.

Keep in mind

He did not respond to GrowSF's June 2026 candidate questionnaire, and no outlet we cite describes his platform — a gap in the record, not a mark against him.
