Rubric: https://voteorelse.com/about#methodology ## On the ballot - **Mark DeSaulnier** — United States Congressman · Democratic - **Jeff Frese** — Small Business Owner · Republican Representative Mark DeSaulnier took 59.7% of the June 2 vote and Republican Jeff Frese took 12.9% to claim the second slot. The district covers central Contra Costa County. The winner holds one of 435 seats in the U.S. House for a two-year term. A member introduces bills, sits on committees that shape federal legislation, votes on the federal budget and on war powers, and handles casework between constituents and federal agencies. Seniority governs committee standing, so a long-serving member carries influence a newcomer cannot. The incumbent has served since 2015 and raised the majority of his funding from committees rather than individuals, which is a different balance from most Bay Area members on this ballot. His opponent has reported no funding. The practical question is what this district gets from a safe seat. ## Mark DeSaulnier Mark DeSaulnier has represented California's 10th District, covering most of Contra Costa County, since 2015, following service on the Concord City Council, the county Board of Supervisors, and both houses of the California Legislature (Danville San Ramon). Before entering politics he worked as a probation officer, truck driver and restaurant manager (Danville San Ramon). In the House he has focused on transportation safety, including the bipartisan Stop Underrides Act aimed at preventing fatal truck underride crashes (congressional press release). In March 2020 he broke multiple ribs and injured his spleen after a fall while jogging near the Capitol; complications led to pneumonia, and he spent nearly five weeks in intensive care, four of them on a ventilator, with doctors telling his family there was "little hope" of recovery (ABC7 News). He recovered and returned to work, and sums up his approach to the job simply: "I work for you" (campaign site). He promises to keep "lowering costs and expanding housing so working families can afford to stay" in the district, and says he will protect medical research funding and reproductive rights (campaign site). He also promises to make sure "workers have a real voice as AI and automation reshape the economy" (campaign site). **Strengths:** A decade in the House plus prior state and local experience, and a full return to work after a serious 2020 health scare. **Trade-offs:** A decade of House votes to answer for, in a chamber where his party has been in the minority for most of it. **Keep in mind:** His 2020 hospitalization was serious and well documented; he has continued a full legislative schedule since recovering. ## Jeff Frese Jeff Frese, a Moraga small-business owner, describes himself as "husband, father, coach, small business owner" (campaign site). He says he built a national snack brand from his kitchen table, sold it, and has since run other consumer companies, framing that as his qualification: "I've made payroll and answered to customers, not donors" (campaign site). This is his first campaign for office; local coverage found that "Republican candidate Jeff Frese doesn't have much information about who he is, his background and his qualifications for the congressional seat" beyond his own materials (Danville San Ramon). He says his focus is "California families and the real challenges we face here: affordability, secure elections, and an economy that works for people who live and work in CA-10" (Danville San Ramon). He promises to cut federal regulations he says drive up housing, energy and food costs, reduce wildfire risk through changes to federal land and forest management, and reform insurance premiums (campaign site; Danville San Ramon). He also backs voter ID requirements, a paper-ballot audit system, an Election Day holiday, and preserving Social Security and Medicare "without cuts or age increases" (campaign site). **Strengths:** A first-time campaign built on private-sector experience rather than a political career. **Trade-offs:** No record in office to judge, and even local coverage found little independent detail about his background. **Keep in mind:** What is documented about him comes almost entirely from his own campaign, not outside reporting. ## Record in office Mark DeSaulnier (Democratic) has served in the U.S. House since 2015 and has sponsored 28 bills in the 119th Congress; 2 of their career bills have become law. Jeff Frese has not served in the California Legislature or U.S. Congress; these records cover only those offices.
