California State Assemblymember James Gallagher (R) clinched victory in Tuesday's special election to fill the House seat left vacant by the death of Rep. Doug LaMalfa (R) in January, adding another Republican to the chamber's narrow majority. Gallagher, who secured President Trump's endorsement, will represent California's 1st Congressional District for the remainder of LaMalfa's term.
According to Decision Desk HQ, Gallagher won 62.4 percent of the vote outright, easily outpacing State Sen. Mike McGuire (D) and Democrat Audrey Denney, who each garnered about 18 percent. In a concurrent primary for the full term, Gallagher led with 47.2 percent, followed by McGuire at 38 percent and Denney at 13 percent as of Wednesday.
Gallagher framed his win as a mandate from voters who want a champion for the North State, echoing LaMalfa's legacy. “In November, we will be running in a new District, drawn not by an independent citizens commission, but in a backroom by my opponent Mike McGuire and other Sacramento politicians,” he said in a statement. “The results tonight indicate that we will do well, as voters are fed up with Gavin Newsom and his chief Lieutenant Mike McGuire, whose policies have made California unaffordable and unsafe for too many families.”
The redrawn district, shaped by Proposition 50 passed last November, now includes the more liberal city of Santa Rosa and parts of Sonoma County. The Cook Political Report rates it as solid blue, setting up a steep climb for Gallagher against McGuire in the general election. This dynamic mirrors other competitive races across California, such as the showdown in the redrawn 40th District and the reshaped contest in the 38th District.
McGuire struck a defiant tone on social media platform X, writing: “Today, the people of Northern California reminded us what democracy looks like. Neighbors showed up. Volunteers stepped up. Voters made their voices heard. When good people come together, they can accomplish extraordinary things — and today we’re on the road to take America back.”
LaMalfa, a rice farmer and lifelong Northern California resident, represented the district since 2013. His death drew tributes from across the political spectrum, with Trump praising him as a “fierce champion on California water issues” and lauding his loyalty. The largely rural district includes Chico and Redding, areas that have long leaned conservative.
Gallagher's immediate task is to navigate a district that has shifted leftward due to redistricting. The November election will test whether his Trump-aligned message can overcome the new Democratic tilt. As California's primary vote counting continues—sometimes stretching for days due to mail ballots, as seen in the ongoing delays—both parties are bracing for a fierce battle in the 1st District.
