The richest spent a fortune on election campaigns. A record was set in California.

An analysis reveals that California's wealthiest residents include more registered Democrats than Republicans, with a significant portion being independents. Among 166 billionaires, 39% are independents, 36% Democrats, and 22% Republicans. Notable Democratic billionaires include Mark Zuckerberg and Sam Altman, while Republicans include Arnold Schwarzenegger. The financial engagement of billionaires in California has reached unprecedented levels, with over $612 million spent on elections. The majority of billionaires reside in San Francisco and Los Angeles, and over 60% have voted in the last three presidential elections. Despite a tendency to support Democrats, the largest group remains unaffiliated with either major party. Upcoming elections will see Americans voting for the entire House of Representatives and 35 Senate seats, with Democrats favored to gain control.
