Lisa Ramirez is running against Young Kim (R, incumbent).
CA-40 is one of four California GOP seats the Cook Political Report identifies as somewhat competitive. Democrats view it as a key flip opportunity in 2026, especially amid shifting Orange County demographics. Young Kim won in 2024 by over 10 points, but Democrats see rising voter disenchantment with Trump policies as their best chance to unseat her.
Ramirez faces a crowded Democratic primary including Christina Gagnier (former school board member), Joe Kerr (2024 nominee and retired firefighter), Esther Kim Varet (art dealer), Perry Meade (labor organizer), Nina Linh (nonprofit founder), and Paula Swift (community advocate). She launched her campaign August 20, 2025 after gaining attention for the Barranco case. Young Kim has nearly $4 million cash on hand.
Key dates to watch: Primary on June 2, 2026 and General Election on November 3, 2026.
