Should political candidates be permitted to use AI-generated tools to criticize their opponents?

Scott Wiener and Connie Chan debated their respective policy stances regarding artificial intelligence, including the regulation of data centers, during an hourlong event hosted by KQED and the San Francisco Chronicle. Wiener, who authored an AI safety law passed in 2025, also apologized for a campaign-deployed AI chatbot that mocked Chan.

Why it matters

The debate highlights a growing tension between legislative oversight of AI and the physical infrastructure requirements of the technology. These policy differences carry significant weight for the San Francisco seat, which has remained unchanged for four decades.

A $500,000 contribution was made to an outside PAC supporting Scott Wiener, highlighting the financial stakes in the congressional race. This follows the 2025 passage of an AI safety law introduced by Wiener after his previous 2023 legislation was vetoed by Governor Gavin Newsom.

The players

Scott Wiener

California state legislator and author of a 2025 AI safety law.

Connie Chan

San Francisco local official and congressional candidate endorsed by Nancy Pelosi.

Gavin Newsom

Governor of California who vetoed a 2023 AI safety bill.

Nancy Pelosi

Long-serving member of Congress who entered office in 1987.

Anthropic

AI research company that contributed to a PAC supporting Scott Wiener.

The details

The candidates presented divergent strategies for managing AI growth within the city. Connie Chan proposed a moratorium on new data centers—large facilities housing the server clusters required to train and run AI models—to curb resource consumption. Conversely, Scott Wiener highlighted his record on legislative safety frameworks, despite acknowledging a mistake in the deployment of an AI chatbot designed to target his opponent.

1987: Nancy Pelosi entered Congress.
2023: Scott Wiener introduced his first AI safety bill.
2025: A scaled-back version of an AI safety bill passed.
September 25, 2026: The congressional debate occurred.

The Tech Race

This race highlights the growing legislative friction surrounding the 2025 California AI safety law. The outcome of the election will determine how the district manages the next phase of AI policy, moving beyond the safety frameworks established at the state level.

Voters should monitor how proposed changes to data center zoning affect local electricity consumption and grid stability. These policy stances directly impact how the city integrates future high-performance computing infrastructure.

The takeaway

The race underscores the transition of AI policy from a technical research concern to a major legislative campaign issue. Residents should track official committee hearings in Sacramento for updates on the implementation of the 2025 safety bill.
