I do not think that his article is cover for his preferred candidate, as it was written a long time ago (2008 I believe).

What I think is this. We all know that our corporate news media is adamantly against Bernie or any other candidate with a similar agenda. We also know that they are adamantly against any talk of exit polls to monitor elections in our country, probably because, as I say in the OP, election fraud almost always favors the more conservative candidate. They want to keep it that way.

So what I believe is that Nate couldn't possible really believe the stupid things that he says in his article. He is obviously way too intelligent for that. I believe that he was pressured to write the article by powerful people who I can only guess at. I believe that he believed that writing it would favorably affect his career or that not writing it would hurt his career, possibly badly. That is the only explanation that makes sense to me.
