I cannot and am not commenting on his articles in general but specifically the one you pasted and the articles he used as reference. What is accurate or truthful about speculation and rumor based on unsubstantiated and unsupported information?
The issue, from where I'm standing, is that article is really out of character for him. He'll touch on the political from time to time, but rarely digs deep. Even he says he's not a political writer so he stays out, so I'm not sure why he wrote that. When he writes what he knows, he's very good. That article is pure, unsubstantiated crap, unfortunately, which isn't something he does very often at all.
