Considering how easy it is to come up with some meaningless name for a front group, such as South Carolina Institute for Electoral Inquiry™, failing to do that smacks of laziness, incompetence, or both.
Or a just plain honest mistake. One of the campaigns I worked on back in 2004 put out a mailer without realizing the paid for information was in the bleed -- we didn't know it was missing until we got our copy in the office PO Box. We freaked out for a while because we thought our opponent would use it against us. Then we looked at his mailers, and discovered that he had made the same mistake.
**** happens.
