Los Angeles City Councilmember Nithya Raman is running for mayor, shaking up the field of candidates one final time.

Raman said she will challenge Mayor Karen Bass, her onetime ally, campaigning on issues of housing and homelessness, transparency and “safety in our streets.”

In an interview, Raman called Bass “an icon” and someone she deeply admires. But she said the city needs a change agent to address its problems.

“I have deep respect for Mayor Bass. We’ve worked closely together on my biggest priorities and her biggest priorities, and there’s significant alignment there,” said Raman, who lives in Silver Lake. “But over the last few months in particular, I’ve really begun to feel like unless we have some big changes in how we do things in Los Angeles, that the things we count on are not going to function anymore.”

Saturday’s announcement — hours before the noon filing deadline for the June 2 primary election — capped a chaotic week in L.A. politics, with candidates and would-be candidates dropping in and out of the race to challenge Bass, who is seeking a second four-year term.

Raman would immediately pose a formidable challenge to Bass. She was the first council member to be elected with support from the Democratic Socialists of America, which scored an enormous victory last fall with the election of New York City Mayor Zohran Mamdani.

At the same time, Raman has deep ties to leaders in the YIMBY movement, who have pushed for the city to boost housing production by upzoning single-family neighborhoods and rewriting Measure ULA, the so-called mansion tax, which applies to property sales of $5.3 million or more.

Raman’s eleventh-hour announcement caps what has been the most turbulent candidate filing period for an L.A. mayoral election in at least a generation. She launched her bid less than a day after another political heavyweight, L.A. County Supervisor Lindsey Horvath, decided against a run.

Until Raman’s surprise entry, the field had seemed to be clear of big-name challengers. Former L.A. schools superintendent Austin Beutner ended his campaign on Thursday, citing the death of his 22-year-old daughter. That same day, real estate developer Rick Caruso reaffirmed his decision not to run.

Bass campaign spokesperson Douglas Herman did not immediately provide comment.

Raman’s announcement comes as Bass continues to face sharp criticism over the city’s handling of the Palisades fire, which killed 12 people and destroyed thousands of homes. Unlike some of the candidates, Raman has not publicly criticized Bass about the city’s preparation for, or response to, the disaster.

Bass, 72, faces more than two dozen opponents from across the political spectrum.

Reality TV star Spencer Pratt, a Republican, has received praise from an array of Trump supporters, including Riverside County Sheriff Chad Bianco and U.S. Sen. Rick Scott, of Florida. Pratt has focused heavily on the city’s handling of the fire, which destroyed his home.

Democratic socialist Rae Huang is running against the mayor from her political left. Huang has called for more public housing and for a reduction in the number of police officers, with the cost savings poured into other city services.

Brentwood tech entrepreneur Adam Miller, who has described himself as a lifelong Democrat, said the city is on a downward trajectory and needs stronger management. The 56-year-old nonprofit executive plans to tap his personal wealth to jump-start his campaign.

Also in the race is Asaad Alnajjar, an employee of the Bureau of Street Lighting who sits on the Porter Ranch Neighborhood Council. Alnajjar has already lent his campaign $80,000.

At City Hall, Raman’s entrance into the mayor’s race is a bombshell, particularly given her relationship with Bass.

In December 2022, not long after taking office, Bass launched her Inside Safe program, which moves homeless people indoors, in Raman’s district.

Two years later, while running for reelection, Raman prominently featured Bass on at least a dozen of her campaign mailers and door hangers. Raman’s campaign produced a video ad that heavily excerpted Bass’ remarks endorsing her at a Sherman Oaks get-out-the-vote rally.

Raman, whose district stretches from Silver Lake to Reseda, ultimately won reelection with 50.7% of the vote. In the years that followed, she continued to praise Bass’ leadership.

In November, while appearing at a DSA election night watch party for Mamdani, Raman told The Times that Bass is “the most progressive mayor we’ve ever had in L.A.”

Last month, Bass formally announced that she had secured Raman’s endorsement, featuring her in a list of a dozen San Fernando Valley political leaders who backed her reelection campaign.

Raman ran for office in 2020, promising to put in place stronger tenant protections and provide a more effective, humane approach to combating homelessness. On her campaign platform, she called for the transformation of the LAPD into a “much smaller, specialized armed force” — but never specified what exactly that would mean.

Since then, the LAPD has lost about 1,300 officers — a decrease of about 13%. The City Council has put in place new eviction protections for tenants, while also capping the size of rent increases in the city’s “rent stabilized” apartments, which were mostly built before October 1978.

Raman does not face the same political risks as Horvath, who had already been running for reelection in her Westside and San Fernando Valley district. Horvath, had she run for mayor, would have had to forfeit her seat on the county Board of Supervisors.

If Raman loses, she would still hold her council seat, since she does not face reelection until 2028.
