You're getting the "kids" mixed up. Mr. Edmunds received the Instant Messages and works for Isatook's campaign. Another young man received the innocuous e-mails. The "e-mail" young man's parents are the one's who were not doing the pursuing. Mr. Edmunds was more than old enough to deal with advances from Mr. Foley...if he had chosen to.
Is it routine to have a 21 y/o college student for a campaign manager?
