Gov. Gray Davis has canceled a controversial fund-raiser with bullet train advocates one day after authorizing a vote on a $9.9-billion dollar high-speed rail bond. The fund-raiser was planned at the Santa Clara home of Rod Diridon, the Davis-appointed chairman of the California High Speed Rail Authority. Republican opponent Bill Simon went to Diridon´s home and set up a podium outside the closed door. The GOP nominee told reporters that Davis´ tactics were corrupt. Diridon had offered to cancel the event after yesterday´s Los Angeles Times and San Francisco Chronicle carried stories about it.
