Incumbent U.S. Representative Sydney Kamlager-Dove, a Democrat, holds a commanding position in the June 2, 2026, top-two primary for California's 37th Congressional District following boundary changes from Proposition 50. Multiple Democratic challengers, including Ryan Duckett, Elizabeth Fenner, Todd Lombardo, and Samantha Mota, along with Republican Baltazar Fedalizo and other minor candidates, are on the ballot in this heavily Democratic Los Angeles County seat. The district's consistent partisan lean has limited opposition fundraising and visibility, with the incumbent's prior primary performance exceeding 70 percent. Trader consensus reflects the low likelihood of any challenger advancing over the sitting member in the nonpartisan primary format.
