With less than three weeks until Election Day, outside groups are pouring millions of dollars into two types of state legislative races: purple districts featuring a Democrat and a Republican, and safely Democratic districts featuring Democrats of different ideological stripes.

Political action committees backed by politically powerful groups such as unions and business have spent over $100 million on California legislative races so far this election cycle, eclipsing 2024 spending. Groups can spend unlimited amounts on “independent expenditures” to boost or oppose a candidate, providing they don’t coordinate with the campaign.

Since they came on the scene in January, two new tech-backed groups have dominated spending in legislative races. Grow California, funded by cryptocurrency investor Chris Larsen and venture capitalist Tim Draper as a “counterforce” to union spending, has spent more than $20 million this cycle. California Leads, funded by Meta and Google, has spent close to $14 million this year to support candidates who are focused on “real-world solutions rather than ideological fights.”
