Trump-endorsed Republican Jim Desmond is leading the race for California’s 48th Congressional District, giving conservatives growing optimism about flipping a key seat in deep-blue California.
Desmond, who currently serves as San Diego County’s District 5 Supervisor, built much of his recent political profile around opposition to the Biden-era border crisis and its impact on communities across Southern California.
According to a recent KGTV-TV and San Diego Union-Tribune poll conducted between May 8 and May 14, Desmond holds a commanding lead heading into California’s June 2 jungle primary election.
The poll shows Desmond capturing 29 percent support — a massive 19-point advantage over fellow Republican Kevin O’Neil, who trails at 10 percent.
The strong showing highlights growing voter frustration over immigration, border security, crime, and cost-of-living issues that have increasingly dominated political discussions even in traditionally Democrat-leaning parts of California.
Desmond has consistently criticized Biden-era border policies, arguing they placed enormous strain on San Diego communities dealing with migrant surges, public safety concerns, and local resource challenges.
And let’s be honest — when Republicans start gaining traction in California on border security issues, that’s usually a pretty strong sign voters are tired of hearing politicians pretend chaos at the border is somehow “working as intended.”
California’s jungle primary system sends the top two vote-getters to the general election regardless of party affiliation, making early polling advantages especially significant.
Supporters of Desmond argue his message aligns closely with President Donald Trump’s America First agenda, particularly on immigration enforcement and public safety. Trump’s endorsement has also energized conservative voters hoping to expand Republican influence in California despite the state’s strong Democratic lean.
As the June primary approaches, the race is drawing increased national attention as Republicans look for opportunities to capitalize on dissatisfaction with progressive policies in major urban and border-adjacent regions.
For now, Desmond’s sizable lead suggests that even in California, issues like border security and government accountability continue resonating with voters far more than political elites may want to admit.
