Spout RW bullshit here or there then defend Obama when he refuses to prosecute torturers or anything Obama did that Bush did as far as foreign policy such as indefinite detention. There is another one. It is the perfect cover.

Now if someone is pushing progressive policies here or there, attacks Republicans when they do something, also criticize Obama when he pushes RW policy. If they are pushing progressive policy, are they really a troll?

How about a list of posters that are suspected and vet them that way? I don't worry about who is a troll so much, I just talk policy. If I like it, I say so. If I don't, I say so. My post history includes supporting Obama on policy choices and criticizing him on others. For a President that describes himself as a "moderate Republican"if this was the 80's), a troll would have an easier time defending those "moderate Republican" policies then push Republican policies elsewhere on DU.
