“Did he change his mind or is he just doing the White House’s bidding?”........
That one pretty much answers itself. He does not want to loose his current job nor his eventual cushy retirement. There are numerous ways he could be “punished” if he failed to do odumbo’s bidding and since he does NOT have a dog in this Syria fight, he has nothing to loose by supporting odumbo. After all, its just spoken words.
Nothing to lose but the blood of our children.....
