Fox does not allow any tea Party friendly people on Special Report or Fox News Sunday panels
No one "sabotaged" anyone, neither FNC nor CNN.
I'm not any kind of media consultant, or expert. But, as a career Naval officer, I have had the opportunity to be at some press functions when Sr. Command was being interviewed by the media (and on one occasion I was the interviewee). At every event, the Navy had professional officers (or SNCOs) whose sole job was to ensure the press event went EXACTLY as planned - camera placement, lighting, mic-levels even makeup, all handled by DoD. They completely own the conditions of the interview.
How do you let a another camera into a single camera event? Does the White House - in any administration - let some cable operator set up wherever he wants for an Oval Office address? Of course not.
If fault is to laid here, it must be laid squarely at the feet of the Tea Party Express, and probably to a lessor degree with Bachmann herself.
