Pelosi's Influence Tested in San Francisco's Fierce House Race
For the first time in nearly four decades, San Francisco's lone House seat is contested not between parties, but between two Democrats, highlighting a shift in local political dynamics.
The race to succeed Nancy Pelosi in California's 12th Congressional District is shaping up to be a defining test of her political influence, as the seat she has held for 39 years is now the focus of an intense intra-party battle.
San Francisco has not seen such a significant contest for its House seat since Pelosi first won it in 1987. This year, the contest is between two Democrats: State Senator Scott Wiener and San Francisco Supervisor Connie Chan. Both candidates align on many progressive issues but differ on approaches to urban development and housing.
In the June primary, Wiener secured 41% of the vote, while Chan garnered 30%, boosted by a late endorsement from Pelosi. Saikat Chakrabarti, a self-funded candidate, received 18% and subsequently channeled resources to support Chan.
Affordability is a central theme in the campaign. Wiener advocates for expanding housing supply through zoning reforms, a stance he has championed during his decade in Sacramento. Chan, conversely, has supported residents opposing large-scale developments and prioritizes subsidized housing and tenant protections. Wiener portrays Chan as an obstructionist, while she labels him as being too close to developers.
Pelosi's endorsement of Chan has brought significant attention to her campaign, aligning prominent local politicians and unions behind the supervisor. Despite this backing, Wiener appears to hold an advantage in fundraising.
Wiener began exploring a run in 2023, even before Pelosi announced her retirement. Reports suggest he may have broken a past understanding with Willie Brown, a long-time San Francisco political figure, not to challenge Pelosi for the seat. Wiener has denied these claims.
Relations between Pelosi and Wiener have been strained, notably in 2024 when she publicly criticized his proposed AI safety bill. The animosity escalated by August 2026, with a chatbot associated with Wiener's campaign making light of Chan, drawing sharp criticism from Pelosi and other Democratic women for being sexist and racist. Wiener apologized and removed the chatbot, later retorting by characterizing Pelosi and Ro Khanna as prolific stock traders in Congress.
Wiener, with his height and media-savviness, is a more visible campaigner, advocating for numerous debates and possessing a statewide profile. However, he has also faced protests, including a confrontation at a Trans March in June over the conflict in Gaza.
Chan, while less of a public performer, excels in local community engagement, connecting with voters in Cantonese banquets and neighborhood doorsteps. Although she lacks Wiener's name recognition, she benefits from Pelosi's established campaign infrastructure. She is also positioned to be the first Asian American to represent the district, potentially serving as a strong advocate for labor unions, while Wiener is seen as the more experienced legislator.
The race is a test of Pelosi's ability to anoint a successor, even in retirement, against Wiener's established campaign momentum. With mail-in ballots being distributed, the outcome remains uncertain. Recent polling shows Chan narrowing Wiener's lead, with a significant number of undecided voters. The election on November 3 will determine who represents San Francisco in Congress, marking a significant shift after nearly forty years of Pelosi's dominance.
