Republican Jim Desmond heads into the general election for California’s 48th Congressional District with significant financial backing and an endorsement from Donald Trump.
While Desmond faces Democrat Marni Von Wilpert in a newly redrawn battleground, his federal campaign is directly fueled by years of high-profile dissents on the San Diego County Board of Supervisors over immigration enforcement.
In April, the National Republican Congressional Committee included Desmond in its 2026 MAGA Majority program, which aims to boost candidates aligned with Trump’s policy agenda.
“Thank you, Mr. President. We’re going to win this race, bring common sense back to California, and make this state affordable for working families again. The people deserve nothing less,” Desmond wrote on X in April after the Commander-in-Chief’s endorsement.
In April 2026, the National Republican Congressional Committee also added Desmond to its 2026 MAGA Majority program, a group that focuses on elevating and supporting candidates who align with Trump’s policy agenda and expanding the House Republican majority
Desmond is gaining significant political support from the right to finance his campaign. He not only received an endorsement from President Donald Trump, but he has also raised over $2.2 million, according to Federal Election Commission findings.
A years-long fight over local sanctuary rules
Desmond has campaigned heavily on immigration, taking a hardline stance and advocating for increased funding for Border Patrol and ICE. He has also backed Trump’s efforts to reverse birthright citizenship.
As far back as 2018, Desmond sided with Trump on a lawsuit targeting California’s immigrant protections, calling the state’s sanctuary laws “divisive” and a threat to public safety.
Desmond has continued to call for stricter border security and has pledged to fix a “broken immigration system,” saying it needs revamping and a “fair system that upholds the rule of law.”
In 2025, Desmond joined other Southern California Republicans in an attempt to repeal a San Diego County Board of Supervisors policy that restricts the use of county resources to enforce federal immigration policies.
Policy L-2 was introduced in 2024 by then-Board Chairwoman Nora Vargas. The resolution prohibited county officials from spending time or resources cooperating with ICE. It also barred ICE from accessing inmates or using county facilities for interviews, and required ICE to obtain a judicial warrant before county officials would honor a detainer request.
It passed the San Diego County Board of Supervisors 3-1 on December 10, 2024. Jim Desmond was the policy’s chief opponent and cast the lone dissenting vote.
Desmond later attempted to get the board to repeal the policy, arguing it made the county a “super sanctuary,” but the board rejected that repeal effort.
National alignment on voting and the border
Desmond endorses the “California Voter Identification, Citizenship Verification, and Registered Voter List Administration Initiative,” which will be on the ballot in November.
This initiative requires voters to show a government-issued ID in person. Organizations such as the ACLU of Northern and Southern California, the League of Women Voters of California, California Common Cause, and the Asian Law Caucus have opposed the measure, labeling it a tactic for voter suppression. Nonpartisan groups like VoteRiders say these laws make it harder for some voters to participate, including low-income, elderly, Black, and Latino voters who are less likely to have a qualifying ID.
In response to a political candidate questionnaire published by the OC Register, Desmond said, “I support legislation requiring proof of citizenship to vote in federal elections. We show IDs to board a plane, buy cold medicine, pick up a prescription, and check into a hotel. The argument that asking for basic documentation is somehow unfair has never held up, and most Americans agree when you ask them directly.”
Voting rights advocates counter that such measures restrict access for eligible voters, but Desmond maintains that stricter verification is necessary to preserve public confidence in elections.
Desmond’s well-known reputation as a local conservative dissenter could influence his chances of winning a swing district. The outcome may depend on whether Von Wilpert can successfully connect him to Trump’s national agenda–a critical factor in one of California’s most competitive House races.
