Scott Wiener leads the market for California's 11th Congressional District seat as the top-two primary winner with 41 percent of the vote in June, well ahead of Connie Chan at 30 percent. Wiener maintains an edge through superior fundraising, substantial outside PAC support, and endorsements from business and tech-aligned groups, while a late-October independent poll showed him at 47 percent to Chan's 41 percent among likely voters. Chan benefits from Nancy Pelosi's endorsement and labor backing but trails in donor networks and media support. Both candidates are competing intensely for Chinese American voters in San Francisco precincts, where housing, public safety, and AI regulation differences have emerged as focal points ahead of the November 3 general election.
