if they were fabricated - he would be out there screaming about it.
otherwise, you are basically telling me that tomorrow - ABC could print fabricated IMs for any other republican congressman they selected (its trivial to fabricate this), and the contents would instantly be true just because ABC published them.
As I mentioned earlier, Foley is in a no-win situation. We have a page who was made uncomfortable by an overly friendly series of emails. We have one page suggesting that everyone was warned about Foley and we have several others who claim that wasn't true. We have ABC News printing a salacious IM conversation that supposedly happened three years ago without any verification. Foley is toast no matter what he does.
