Who’s Bankrolling the No on 89 Campaign? Mercury Insurance—Controversial California Insurance Corporations- First to Fund Attacks on Anti-Corruption Initiative
The California Chamber of Commerce is busily building its team of Sacramento insiders desperate to support the status quo-and ignore the corruption that troubles so many voters. Their first major donor has stepped to the plate, with Mercury General Corporation donating $100,000 to the No on 89 campaign, paired with another $100,000 from George Joseph, the company’s CEO.

On the opposite side is the California Nurses Association and many good government advocates, the SF Democratic Party , SF People's Organization, SF Green Party, and community-based organizations up and down the state ...

Rose Ann DeMoro, Executive Director of the California Nurses Association noted, “Mercury Insurance is symbolic of the problems California faces. They give money to any politician who rewards them special favors or treatment. With corporations like Mercury running the show in Sacramento, ordinary voters don’t stand a chance. Prop. 89 is our opportunity to rein in the special interests corrupting out government and clean up the mess in Sacramento.”
