Incumbent Los Angeles Mayor Karen Bass secured her spot in the November runoff election Tuesday night, advancing alongside billionaire developer Rick Caruso after a bruising primary that exposed deep divisions over the city’s direction. Bass, a former U.S. representative and social worker, finished first with 43% of the vote, while Caruso, a Republican-turned-independent with deep pockets, claimed 29%—a margin that stunned analysts who had predicted a far tighter race. The runoff will mark only the third time in modern history that Los Angeles voters have chosen between two non-incumbent candidates for mayor.

The runoff comes after a primary that saw an unprecedented 24 candidates vie for the top spot, setting spending records and drawing national attention. Bass’s campaign emphasized her work expanding housing programs and her rapid response to the homelessness crisis, while Caruso leaned into his reputation as a job-creating developer and his pledge to restore "law and order" without defunding police. Polls ahead of the primary had shown both candidates locked in a tight contest, but Bass’s ground game in core Democratic neighborhoods and Caruso’s dominance with affluent voters reshaped the race.

Caruso’s campaign spent over $40 million—much of it his own money—on television ads and outreach, outspending Bass’s $18 million war chest by more than two to one. Yet Bass’s coalition of organized labor, progressive activists, and Latino voters held firm in key districts like Boyle Heights and South Los Angeles, while Caruso’s support surged in wealthy enclaves like Brentwood and Pacific Palisades. The runoff will test whether Caruso can broaden his appeal beyond affluent voters or if Bass can peel off enough independents to cross the 50% threshold.

Analysts say the runoff will hinge on three critical issues: homelessness, public safety, and economic inequality. Bass has framed Caruso’s approach to policing as a return to failed policies of the past, while Caruso has accused her administration of enabling crime by diverting funds from law enforcement. The debate over homelessness—where Los Angeles has the largest unsheltered population in the country—has become a flashpoint, with Caruso promising to clear encampments within 90 days and Bass advocating for a mix of temporary housing and long-term solutions.

The runoff also arrives amid a backdrop of rising frustrations over street conditions, with Angelenos citing potholes, graffiti, and uncollected trash as top concerns. A recent city audit found that 40% of Los Angeles’s major roads are in poor condition, a figure Caruso has seized on to argue for his pro-business approach. Bass, however, points to her $1.2 billion investment in street repairs as proof her administration is addressing infrastructure woes. The November election will determine which vision voters prioritize in a city grappling with stark contrasts between affluence and poverty.

Los Angeles’s political landscape has shifted dramatically since the last mayoral runoff in 2013, when Eric Garcetti defeated Wendy Greuel. This year’s race reflects a city divided not just by policy, but by visions of its identity. Bass’s supporters see her as a champion of equity and social justice, while Caruso’s backers argue Los Angeles needs a leader who can cut through bureaucracy to deliver results. The runoff campaign will kick off immediately, with early voting beginning October 11 and election day set for November 8. Both candidates have signaled they’ll focus on door-to-door outreach and digital advertising to sway undecided voters in a city where 58% of residents identify as Democrats but 38% lean independent.

The runoff also carries implications beyond Los Angeles. As the nation’s second-largest city, the outcome could influence how other urban centers balance progressive policies with economic growth. With control of the mayor’s office up for grabs, the race underscores the growing influence of self-funded candidates and the enduring power of grassroots organizing in municipal politics. For Bass and Caruso, the next five months will test not just their policy proposals, but their ability to unite a fractured city behind a shared vision for its future.
