As political incidents go, this seems to be one of failing to pay attention to detail not one of malice. On the other hand, Steve Benen reports that Michigan Republicans have undertaken "repeated efforts to record Democratic gatherings with a spy camera mounted to eyeglasses." Benen doesn't undertake speculation about whether Michigan Republicans eschewed Google Glass because the product is still too expensive or because they consider it passe. These spies are not "trackers" that every campaign expects to shadow them. Instead the people with the spy glasses are told "misrepresent themselves when attending events."
. . .what’s striking is the operation itself. Parties on both sides may rely on trackers as a matter of course, but it’s highly unusual – indeed, it’s arguably without precedent – for a state party to launch a deliberate spying operation, get caught, and accidentally leave behind evidence documenting the scope of that operation. [Benen 7/21/14]Weiland's people should have edited the video more carefully. Weiland, however, certainly did not claim to be anything other than a Democratic candidate for the United States Senate, and I'm pretty sure nobody was filming with spy glasses.
