The obvious explanation seems to escape the media. Those are impostors from the left who are infiltrating the Tea Party Movement to discredit the movement. They do it all the time so why is it invisible to the media.
Yes, I know the answers but it is necessary to pose the question.
These “impostors” should be photographed, and discretely followed, to see where they go, etc.. They must be exposed and identified for what they are!
