ABC's Teddy Davis reports: An already ugly health-care debate got even uglier on Wednesday evening when a 65-year old opponent of Democratic reform proposals had his finger bitten off at a vigil organized by MoveOn.org in Thousand Oaks, Calif."My understanding is that it was a supporter of health care reform who got into a confrontation with a non-supporter and the non-supporter got his finger bit off," Capt. Bruce Norris of the Ventura County Sheriff's Department told ABC News. "My understanding is that the event was organized by MoveOn.org."
