It's obvious to anyone who's been on political message boards for a long time that trolls play both sides of the street. In the current environment, that means some trolls pretend to be lefty opponents of President Obama, and others pretend to be diehard supporters of him.

"But why would trolls pretend to be Obama supporters?" I've been asked, incredulously. "Surely they don't want it to appear that the President has support!"

Because by pretending to be super-supporters, trolls can demean, diminish and ridicule real Obama supporters who have legitimate concerns and criticisms about the President's actions, thus driving a wedge between the President and some of his own staunchest supporters.

I don't believe that all hardcore Obama supporters are trolls, by any means. But I've been around long enough to know that, if there's a wedge to be driven, the trolls are working it from ALL the angles.
