If your opponent has gained the reputation of playing tricks like this (earned or not), point the finger at him even when it is your own campaign at fault.
Ted himself admitted it has been tracked to a local volunteer in HI they have asked to cease and desist. So it came from his team, just not from the official team apparently.
Another interesting thought from Ted. He stated that when a campaign is flailing and failing what they do is attack. Question: How then should we interpret his speeches over the coming days when he attacks Trump?
