And the myriad electronic devices his staff and security people have to have doesn’t give his position away?
You may very well be right about giving his position but I think you are referring to his physical (gps) position.
My take on his umbilical connection to his Blackberry is that his handlers need to have a telepromting leash on him. He does quite well responding to situations where he can read responses from a screen.
In an impromptu environment, he stammers and stutters his way through an answer. It is my judgment that he is the ultimate stealth president and is being controlled by others and the Blackberry is but one way in which that is done.
