Across the Bay
The debate centered on the regulatory legacy of the 2025 state AI safety law, reflecting a broader divide in local politics. The candidates' competing platforms follow a pattern of legislative tension between tech growth and safety measures seen in Sacramento.
Voters must now weigh whether to support a candidate proposing a moratorium on new data centers or one focusing on state-level AI safety legislation. This choice will shape the regulatory environment for tech infrastructure projects within the city.
The takeaway
Voters should review the candidates' specific proposals on data center density and AI oversight before heading to the polls. Watch for future candidate forums to see if these policy differences continue to define the congressional race.
