Overview

Mark DeSaulnier is a Democratic member of the U.S. House of Representatives from California with 525 recorded votes. His voting record reflects consistent alignment with progressive policy positions across a range of issues, positioning him to the left of the typical House Democrat. On domestic policy, DeSaulnier has voted in favor of most healthcare and education measures that came before him, supporting roughly two-thirds of bills in each area. He has opposed the majority of budget and spending bills (voting yes on only about 18%), which typically reflects disagreement with the spending priorities or cuts proposed in those measures. He has also opposed most bills categorized under banking and finance, criminal justice, and immigration. In foreign policy and defense, DeSaulnier supported the vast majority of foreign policy votes (approving about 91%) and backed most defense-related measures (71%), though he voted against the fiscal year 2027 National Defense Authorization Act. He supported legislation related to veterans' care and voted in favor of invoking the War Powers Resolution regarding U.S. forces in Lebanon, suggesting support for congressional oversight of military operations. On labor issues, DeSaulnier voted in favor of 80% of measures, and he supported most infrastructure and agriculture bills. His votes on environmental and energy matters show him opposing about two-thirds of the bills in that category, which in the current Congress often reflects opposition to measures that would roll back environmental regulations.
