Whether it's Maddow or Couric or whoever, they're a lot more organised and in sync than you'd think - and I suspect there's a whole lot of behind the scenes coordination going on.
I believe that they're designed to destroy whoever appears to be a threat - Sarah found that out - as has Rand Paul.
What I don't know is if it's legal for the white house to coordinate these things behind the scenes. We know they distribute their talking points and bobble-heads in the media regurgitate whatever their masters decree. But is it legal to actively seek certain outcomes?
