Mark DeSaulnier

California's 10th congressional district

CA-10 Midterms Intelligence

Mark DeSaulnier sits in one of California’s safest Democratic seats: CA-10 is D+33, gave Democrats 66.5% of the vote, and left him uncontested in 2022. The district’s political identity is affluent, highly educated, and suburban Bay Area, with a median income of $153,525 and home values topping $1,029,400. Its defining feature is a multiracial professional class—especially a large Asian population—paired with older homeowners and commuters who expect government to work on transportation, schools, and quality-of-life issues more than ideological spectacle.

For advocates, this is a persuasion play aimed less at partisan conversion than at aligning with district sensibilities: competence, affordability, and tangible public benefit. Cost pressure is the soft underbelly—high housing costs and a $2,658 median rent create anxiety even in a wealthy district—so messages that connect infrastructure, health, or workforce policy to economic stability and daily convenience will travel. DeSaulnier’s committee footprint makes ethics-safe, implementation-focused asks on transit, education, and labor especially viable.

Representative Mark DeSaulnier represents California's 10th congressional district, serving 760,299 constituents. The district has an estimated median household income of $153,525 and an unemployment rate of 5.5%.
