The real question is Whether the first article he posted " The lion Unleashed" is really from The Economist or not.
Yes it is, I hope you know how to click on links.
As for the rest of your post, yes, for MQM/Musharraf/Zardari admirers, the article may seem biased. Also, theres nothing superficial about the stuff you quoted, especially the prediction his party made about him getting the CJ back in a week, even I read that in news articles.
