They’re not even attempting to disguise their motives any more.
But they don’t have nearly enough confidence to make a declarative statement about it.
None of them do, now or ever. Whether they work independently or in consultation. Not the trolls, not those occupying the many degrees of separation between the mindless trolls and the Obama administration.
