On the ballot

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

Assemblymember Blanca Rubio took 65.3% of the June 2 vote and Republican Dan T. Tran took 34.7%; they were the only two candidates on the primary ballot. The district covers the San Gabriel Valley around Baldwin Park and West Covina.

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. Seniority compounds: a member several terms in chairs committees and shapes which bills reach a floor vote at all.

June's margin tells you where this district's registration sits. The incumbent has raised more than $1.3 million against an opponent with no reported fundraising at all, and $678,300 of it came from businesses and other organizations. Weigh a mid-range enacted record against one of the most business-funded campaigns on this ballot.

Blanca Rubio

Democrat, the sitting Assemblymember for this district. She is lead author of 31 bills in the 2025–2026 session, 5 of them signed into law. She raised $1,303,715, among the larger Assembly totals on this ballot.

Strengths

Five bills signed into law this session and the committee standing that comes with multiple terms.

Trade-offs

Effectively none of her support arrived in amounts under $100 — a seat funded by organizations rather than by the people who vote in it.

Keep in mind

More than $1.3 million raised against an opponent with no reported fundraising is worth noticing, whatever conclusion you draw from it.

Dan T. Tran

Republican, and the only other candidate on this district's ballot, with 34.7% of the June vote. He has not served in the California Legislature or U.S. Congress. Cal-Access shows no contributions reported for his committee.

Strengths

He took more than a third of the June vote with no reported campaign funding at all.

Trade-offs

No money and no record in office leaves very little for a voter to evaluate beyond party.

Keep in mind

Coverage surfaced almost no biographical or platform detail about him. That gap is what was available to us on 2026-08-10, not a comment on his candidacy.
