Hollywood is about to show California who really runs the show—and it's happening on Tuesday.

The entertainment industry's biggest names and deepest pockets are converging on the Golden State's primary elections, with major contributions and glitzy fundraising galas backing contenders for governor and the Los Angeles mayor's office, according to Deadline Hollywood.

Hollywood insiders say the celebrity donor class has been unusually hands-on with their chosen candidates, making these races personal in a way not seen in years.

The governor's race is drawing A-list fundraisers packed with power players writing six-figure checks. The LA mayor's race has become a battle for control of the entertainment capital itself.

Industry sources reveal that candidates have focused on courting the celebrity vote, understanding that in Hollywood, star power wins elections. From Tinseltown penthouse events to exclusive beach house cocktails, the money is flowing.

What makes this cycle different? Insiders say contenders have paid serious attention to issues that actually matter to the entertainment community, rather than taking their support for granted as in previous years. The strategy appears to be working: Hollywood is giving early and giving big.

The stakes are high. Whichever candidates emerge victorious from Tuesday's primary will face off in November's elections, potentially reshaping California's political landscape for years to come.

Tuesday's vote could reshape not just California politics, but the entire entertainment industry's influence in Washington.
