When I read supposedly “objective” writing about politics, I generally assume that the author is left-of-center himself and that he’s writing from his own point of view, regardless.
I've found that to usually be the case as well.
Anyone who doesn't have a clear opinion about issues isn't listening.
True objectivity is a very rare thing and is usually only announced as a smokescreen to hide an agenda.
I'd much prefer that people simply be honest about their perspectives.
As Rush says, "middle-of-the-roaders just get run over" :-)
