A proposed ballot initiative seeks to give the California Department of Insurance the same rate-setting authority over health insurance that it already holds over auto and property coverage. Several high-profile business names, such as San Francisco hedge-fund manager Thomas Steyer and agribusiness magnate Stewart Resnick, have contributed to the proposed ballot measure. These contributions were among $1.5 million in donations reported Monday to the California Secretary of State by Consumer Watchdog, the Santa Monica group leading the ballot drive according to a report in the Los Angeles Times.
