Resignation II

Following Shenseki's resignation/firing we have the Obama mouthpiece, press secretary Jay Carney resigning.  Wow!.  Here is a guy that gets more air time than Obama himself.  He is in front of the camera's every day, dodging reporter's softball questions.  Despite recent setbacks to the administration the reporters, even the Fox News guys, are failing to ask hard questions, you know the "Who,Where,When,What,and Why" kind.  Instead they ask "What does so-and-so think about what somebody else said" kind of question.
  You would think being press secretary would be fun.  You get a lot of TV exposure, it's easy to look sharp going up against newsies, you don't have to get armies of civil servants to actually do something to justify their salaries, in fact you don't have to produce much of anything at all.  You look good on nationwide TV for just selling the Administration's line.  Indoor work, no heavy lifting. 
   And yet Carney is sufficiently burned out to toss the job when it was his for the rest of Obama's term in office.  I used to do a bit of selling in my time.  The one thing I learned, is to make the sale, you have to believe in the product yourself.  The customer's can read you, they can tell when you are bending the truth (lying), and when they do, that sale is dead.
   Could it be that Carney has lost his belief in the Obama product?  And hence his ability to sell it on TV?
