Is Jay Carney really that Stupid?

I have watched many of the Briefings by Jay Carney.  I can't decide if he is really that stupid or if he has just drank too much of the Obama Koolaid.

I think the part that has driven me more mad is that the press has for the most part let him get away with his half truths and outright BS that he has thrown out for the past several years.  Thankfully that is slowly falling apart and they are now starting to call him and the Administration out on it.

I watched yesterdays briefing and was just amazed at how hard he tried to circle around the truth and not answer the questions about Benghazi and the new email information that has come out.  He on more than one occasion got tripped up in the BS that he was trying to put out.  Thankfully the Press has decided more and more to press him on the issues and not just buy the stuff he tries to sell.

However, this still begs the question, is he really that stupid?
