This change is reflected in the primary results, where Desmond secured nearly 41% of the vote, while von Wilpert came in second with 19.7%. The race highlights broader trends in California politics, where moderate candidates are gaining traction over more progressive challengers.
The Rise of Jim Desmond
Jim Desmonda well-known figure in local politics, has leveraged his extensive experience and name recognition to secure a strong lead in the primary. As a former mayor of San Marcos and current county supervisor, Desmond has built a solid reputation among voters. His campaign has been bolstered by endorsements and support from key figures, including former President Donald Trump.

Political analysts suggest that Desmond’s experience and local connections have made him a formidable candidate in a district that has become increasingly competitive.

Local Democratic officials have rallied behind her, citing her electoral record and policy expertise as key strengths. Her campaign has also benefited from substantial financial support, raising over $1.25 million, more than any other candidate in the field.
Broader Political Trends
The results in the 48th District race are part of a larger pattern in California politics, where moderate candidates are outperforming more progressive challengers. This trend is evident in other high-profile races, including the gubernatorial campaign, where Xavier Becerra is leading against progressive billionaire Tom Steyer.
Within the Republican Party, there is a notable shift towards far-right candidates. In the race for a San Diego state Senate seat, Kristie Bruce-Lanea far-right candidate, is leading against more established Republican Ed Musgrove.
