margin

Los Angeles Councilmember Nithya Raman has taken a wide lead over incumbent Karen Bass in the L.A. mayor’s race, according to a new poll released Wednesday, although a high percentage of voters remain undecided less than two weeks before mail-in ballots are sent out for the Nov. 3 election.

Raman is favored by 39% of likely L.A. voters, compared with 28% for Bass, according to the poll by the UC Berkeley Institute of Governmental Studies, which was co-sponsored by The Times. The poll found that 33% of voters were undecided.

“Raman clearly has the advantage. Her task is a little less onerous than Bass’,” said Mark DiCamillo, the director of the Berkeley IGS Poll.

Adding to Bass’ low poll numbers are high unfavorability ratings.

The mayor had 63% unfavorable ratings, the poll found, with 28% favorable and 9% having no opinion. By comparison, 40% had a favorable view of Raman, according to the poll, while 39% said they had an unfavorable view of her and 21% had no opinion.

The survey released Wednesday was conducted online with a sample of 2,150 likely city voters between Sept. 15 and Sept. 20. It has a margin of error of about 3 percentage points.

The poll represented the strongest showing yet for Raman, who trailed Bass in almost every poll during the primary campaign and who came in second to Bass in the primary election, with 29% of the vote compared with Bass’ 34%.

Even so, DiCamillo said the large number of undecided voters means the race is far from over.

“It’s extraordinarily unusual to see this many undecided voters at this point in the race,” he said. Mail-in ballots will be sent out beginning Oct. 1, local elections officials say.

The large number of undecided voters can be linked to the elimination of mayoral candidate Spencer Pratt in the June 2 primary, according to DiCamillo. The former reality TV star received 26% of the vote in the primary, and most of the voters who cast ballots for him — 63% — say they haven’t decided whom to vote for in the runoff, the poll found.

Among those Pratt voters who have decided, 22% favored Bass compared with 16% for Raman.

One of the most significant findings in the poll was a massive “generational divide” among L.A. voters, DiCamillo said.

Raman, 45, dominated the 72-year-old Bass among younger voters, with 66% of likely voters ages 18 to 29 choosing the council member while just 4% chose Bass, according to the poll.

Raman also had 64% of likely voters ages 30 to 39 compared with Bass’ 12%, and the council member had 50% of likely voters ages 40 to 49 compared with Bass’ 18%. Raman also was leading among voters 50 to 64 years old by a slim margin of 35% to 33%.

Bass, meanwhile, led among the oldest set of voters — those 65 and up — but not by the same margins. Bass had 41% of likely voters in that group compared with Raman’s 21%.

The mayor has had negative favorability ratings since the 2025 Palisades fire.

According to the poll, 56% of likely voters thought Bass did a poor or very poor job responding to the disaster, which killed 12 people and destroyed more than 4,000 homes, including Pratt’s.

Fourteen percent of the likely voters thought Bass had done either an excellent or a good job and 17% thought she had done a fair job.

The most important issues to likely voters were fixing city infrastructure, moving homeless people indoors, crime and public safety, and building more affordable housing, the poll found.

The poll shows Raman leading in nearly every geographic area of the city. Bass was leading in South Los Angeles and the Harbor region, 37% to 34%, but central Los Angeles as well as northeast and the east side of Los Angeles broke strongly for Raman.

The San Fernando Valley went 34% to Raman and 26% to Bass with 40% still undecided. The Westside favored Raman by a single percentage point, at 35% to 34%.

Raman has led in other polls recently, though none by as wide a margin as in the Berkeley IGS/L.A. Times poll. Shortly before the primary, a separate Berkeley IGS/L.A. Times poll showed Raman leading Bass in a potential head-to-head matchup by just four percentage points, with 32% support compared with the mayor’s 28%.

But the gap between the two has widened since then, the latest poll found, as Bass weathered a difficult news cycle, including rising homelessness numbers citywide as well as the fallout from the Lineage warehouse fire in Boyle Heights that burned for nearly a week, leaving rotting food and a rancid stench in the neighborhood for more than a month.

Raman, meanwhile, picked up largely positive headlines this summer. She gained key endorsements from the carpenters’ union and Unite Here Local 11, the union representing hospitality workers at hotels and the airport, as well as an endorsement from the Democratic Socialists of America. Street homelessness also dropped in her district, which she said was due to her office’s strong outreach, though the Bass campaign credited the mayor’s Inside Safe program for the reduction in Raman’s district.

On the negative side, Raman was booted from her position in the council as chair of the Housing and Homelessness Committee, a move she said was politically motivated.

In an internal Raman campaign poll from early September, the council member was ahead, 44% to 39%, with 17% undecided. She was also leading, 38% to 32%, in a poll commissioned by the group Streets for All, which is backing Raman.

In an early August poll commissioned by an independent expenditure group supporting Bass, the mayor had the edge, 41% to 35%, with 24% undecided.
