No, they are not mouthpieces for active duty. They are mouthpieces for the DNC.
The DNC had this battleplan leaked about 6 weeks ago. Their Clinton generals would be orchestrated to speak out incrementally all the way to October.
EVERYTHING happening this year is the MSM cooperating with a grand DNC strategy to take Congress. The one mistake they are making is they are fighting the battle with last decade's tools. The web forms opinion now, not the MSM.
They will not take Congress if YOU volunteer your time and money to GOP candidates in vulnerable districts.
There are a LOT of active duty with no use or respect for Rumsfeld. And with most of the officer core Republican (roughly 90%), it isn't likely they are all democrat plants. In the O-4/5 range, I'd say about 50% dislike Rumsfeld, but that percentage is growing.
One needs to accept the possibility, at least, that some of these guys care about the US and are speaking out because Rumsfeld is not doing an acceptable job.
And look at how easy it is to get even Freepers to fall for this bilge. Dragging a fish across the trail distracts even our bloodhounds.
