"Sources tell me they have seen a memo from David Quintana, the legal counsel for the California Nations Indian Gaming Association, that was sent to tribal leaders. In it Mr. Quintana raised a warning flag about Mr. Schwarzenegger's positions and his reliance on several aides to former governor Pete Wilson, a skeptic on the expansion of Indian gambling. "This is war, we're going after Arnold Schwarzenegger," the memo concluded. The decision to invest in an effort to stop Mr. Schwarzenegger was made at a private strategy meeting last month, from which several more-moderate tribes were excluded. Participants discussed the need to keep Mr. McClintock in the race on "life support."
