San Jose Mayor Matt Mahan's campaign for governor is collapsing. Key committees are shutting down, a major donor requested a refund, and an ethics complaint has been filed.
Polling shows Mahan in sixth place with only 4% support, down from 7% earlier this month. The campaign has raised $15 million but trails far behind billionaire Tom Steyer's $197 million.
The top two candidates in the June 2 primary will advance to a runoff in November.
