# CA-45 — 2026 U.S. House Race ## PRIMARY RESULT — Tran & Vo advance; Prop 50 reshapes the seat (June 2, 2026) The June 2 top-two primary advanced Democratic incumbent **[[Derek Tran]]** (~50%+) and Republican **[[Chuong Vo]]** (~16%) to a November general (third-place Republican Chi "Charlie" Nguyen ~12.5%). The dominant change is [[Gavin Newsom]]-backed **Proposition 50**, which made CA-45 meaningfully bluer (roughly D+4 → D+8), materially improving Tran's footing after he won the seat in 2024 by just 613 votes. **Key takeaway:** Prop 50 converted one of the closest seats in the country (613-vote 2024 margin) into a Democratic-leaning district (Cook: Likely D as of Sept 25, 2026) — and the November contest is a co-ethnic Vietnamese-American matchup ([[Derek Tran]] vs. [[Chuong Vo]]) for the politically active Little Saigon electorate. ## Snapshot Straddles Orange County and a slice of LA County — Little Saigon (Garden Grove, Westminster), plus Fullerton, Brea, Fountain Valley, Cypress, and Cerritos/Artesia; home to the largest Vietnamese-American population outside Vietnam. **[[Derek Tran]]** (D) flipped it 50.1–49.9 over two-term Republican Michelle Steel in 2024. After Prop 50, the lean moved to roughly **D+8**; Cook rates it Lean Democratic. ## Incumbent **[[Derek Tran]]** (D). Freshman; attorney, Army veteran, and son of Vietnamese refugees — the first Vietnamese American to represent the district. Advanced from the top-two primary with ~50%+ of the first-round vote. ## Republican challenger **[[Chuong Vo]]** (R) — retired law-enforcement officer and former Cerritos City Council member (mayor 2022–2023). Advanced second (~16%); running an ethnic-coalition play for the Little Saigon vote against a co-ethnic Democrat. The Republican first-round vote (~28–30% combined) ran well behind Tran in the bluer district. ## Ratings history | Outlet | Current | Prior | Shift | |---|---|---|---| | [[Cook Political Report]] | Likely Democratic | Lean Democratic | Current per Cook's Sept 25, 2026 House ratings; was Toss Up before Prop 50 | | Sabato's Crystal Ball | (unconfirmed) | — | — | | Inside Elections | (unconfirmed) | — | — | **Context**: Prop 50 (~64–65% yes, Nov 2025) suspended the independent-commission maps in favor of Democratic-drawn lines through 2030, a counter to Texas's mid-decade GOP redistricting. ## Key dates - **June 2, 2026** — top-two primary — completed (Tran & Vo advance) - **November 3, 2026** — General election ## Money Reliable Q1 2026 fundraising/COH figures for the CA-45 candidates were not available; the partisan shift is the larger variable in this cycle. ## Intel notes - **Prop 50 is the dominant variable.** It converted a 613-vote toss-up into a Lean-D seat, sharply improving Tran's footing. - **Co-ethnic matchup.** Tran vs. Vo is partly a fight over Little Saigon's historically GOP-leaning, politically active Vietnamese electorate. - **Weak GOP first round.** A fragmented Republican vote (Vo + Nguyen) and Tran's ~50%+ share signal a weak early GOP position, though SoCal late-mail counting can tighten margins. ## Outside-money log — FEC Form 24 notices ### Receipt date 2026-10-08 — $1,015,758.00 from [[Fairshake PAC]], all positive On e-file receipt date **2026-10-08** the crypto industry's [[Fairshake PAC]] (FEC committee **C00835959**) filed a single Form 24 notice — file **2018439**, an original (`F24N`) received at **16:08:07** — carrying **$6,115,866.36 across six House races**, every line **supporting** the candidate.
