I don’t know who’s advising Cain - but this was a blunder.
I saw the video of the event - and the audience was not booing the military guy - they were booing in agreement with what the military guy said. If the audience had cheered, then Cain’s assessment would have been correct.
This kind of over-reaction is what happens to a novice. It’s better to wait and comment later when you’ve had a chance to see the video and hear the audience reaction.
Cain's Director of Communications resigned yesterday as did his Assistant Director of Communications, and his new Director of Communications unofficially took over for him as of yesterday I believe. (The official announcement of Gordon's addition was supposed to be this Monday but appears to be out on the net now.) His name is J.D. Gordon, and he used to do public relations when he served in the military, therefore you will see him associated with Donald Rumsfeld as he was working under Donald Rumsfeld's command when Donald Rumsfeld was Defense Secretary under G.W. Bush. When Gordon retired from service a couple years back, he started a PR business, and some of his new consultation work included advising and coordinating events for Sarah Palin as of late. He accepted Cain's job offer to work as his Director of Communications, and that is the change that occurred yesterday in his campaign staff.
