Mark DeSaulnier, the Democratic incumbent, advanced comfortably from the June 2026 top-two primary in California's 10th congressional district with nearly 60% of the vote, while Republican Jeffrey Frese secured the second spot with under 13%. The district carries a D+18 Partisan Voter Index and has consistently favored Democrats by wide margins, including DeSaulnier's 66.5% win in 2024. Nonpartisan ratings from the Cook Political Report, Sabato's Crystal Ball, and others classify the seat as Solid or Safe Democratic. These structural factors and the primary results underpin traders' strong consensus for a Democratic victory on November 3. An upset would require an unforeseen late development such as a major scandal or health event affecting the incumbent, or an unusually sharp national partisan swing.
