Javier Lopez is running against Adam Gray (D, incumbent).
CA-13 was the closest House race in 2024—Gray defeated Republican John Duarte by just 187 votes out of 210,000 cast. The district has a Cook PVI of R+1 and Trump won it in 2024, making it one of the most vulnerable Democratic-held seats in the country.
Lopez is the first Republican to enter the race against Gray. Republican consultant Duane Dichiara announced plans to direct significant outside funding to flip CA-13 along with the 9th and 21st districts. Gray and Duarte traded this seat in consecutive elections (Duarte won by 564 votes in 2022, Gray won by 187 in 2024).
Key dates to watch: Primary on June 2, 2026 and General Election on November 3, 2026.
