California’s 27th congressional district holds a June 2 top-two primary that will advance the two leading candidates to the November general election. Incumbent Democrat George Whitesides, who flipped the seat in 2024, benefits from Proposition 50 redistricting that removed conservative portions of northern Los Angeles County and shifted the district toward stronger Democratic performance in recent cycles. He faces low-profile Democratic challengers Caleb Norwood and Roberto Ramos along with Republican Jason Gibbs, a Santa Clarita city council member. No major recent endorsements, fundraising surges, or campaign events have altered the field ahead of the primary, leaving the contest focused on voter turnout among Democratic-leaning suburbs and the Antelope Valley.
