State of California
Member of the State Assembly, District 19
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. 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.

1Philip Louis Wing has no contributions reported to Cal-Access for this race.
2Figures are CA Form 460 filings through June 30, 2026 by committees controlled by each candidate, and can include transfers from a candidate's earlier committees. Semi-annual reports covering January–June 2026 were due July 31, 2026, so some totals lag a period behind. Per the California Secretary of State's Cal-Access raw data export, retrieved 2026-09-21.
3Philip Louis Wing has no itemized contributions dated after the June 2, 2026 primary reported to Cal-Access yet.
4Total is itemized (Schedule A) contributions and self-funding loans dated after the June 2, 2026 primary, through June 30, 2026 — small-dollar unitemized (under $100) contributions aren't independently dated in Cal-Access's raw export, so they aren't reflected here and this may undercount true small-donor activity since the primary. This also doesn't include money reported only on 24-hour late-contribution reports (Form 497) that haven't yet appeared in a periodic Form 460 filing.
