State of California
Member of the State Assembly, District 54
This person holds your district's seat in the California State Assembly (2-year term).
Assemblymember Mark Gonzalez took 99.7% of the June 2 vote. Republican Alexandra Briseno took 0.3%. The district covers downtown and east Los Angeles.
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. Committee assignment is where most of the leverage sits, and it is handed out by the majority's leadership.
A 99-point primary margin means the practical question in this district is not who wins but what the incumbent does with a seat he holds without contest. His enacted record is among the strongest on this ballot and his funding is among the most institutional; both are worth weighing on their own terms, because the ballot will not do it for you.
Mark Gonzalez
Mark Gonzalez chairs a nonprofit community health clinic. He spent six years leading the Los Angeles County Democratic Party before he was elected to the Assembly in 2024. He grew up in Section 8 housing, raised by a single mother. After her stroke he became her caregiver. He says that showed him where government and health care fail vulnerable seniors. The Assembly Speaker appointed him Majority Whip. He has authored bills on price gouging, small business permits and public safety.
He says his mother's stroke, and what he saw caring for her, is why he ran for office. In 2026 he introduced a bill. It would bar anyone who has taken part in federal immigration enforcement from working as a California public employee.
He promises to protect abortion access. He wants to raise wages for working people and expand health coverage regardless of immigration status. He says he will work for more affordable housing, keep guns off the streets, and increase funding for firefighters and paramedics.

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.
3Alexandra Briseno 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.
