Incumbent Democrat Mike Thompson faces a competitive primary challenge from well-funded Democrat Eric Jones in California's top-two primary for the 4th Congressional District on June 2, 2026, under the state's nonpartisan system where the top two vote-getters advance regardless of party. The district, redrawn narrower Democratic after Proposition 50's passage in November 2025, rates D+17 per Cook PVI, with six Republicans and one independent likely splitting opposition votes to enable a Democratic sweep. Recent certified candidate lists from March 26 highlight Jones leading receipts at $3.2 million versus Thompson's $3 million, though Thompson holds more cash on hand; no public polls exist, leaving trader sentiment focused on fundraising edges, endorsements like Democratic Party backing for Thompson and Our Revolution for Jones, and turnout in this safe Democratic seat.
