Re: Imran Ismail attacked by MQM goons
I think that is fine. It is political process. One votes ‘party A’ then next time the person votes ‘party B’, no problem. Actually, if you read my post, I have only said that there should not be any rigged voting, not only in Karachi but all over Pakistan, that is all. I also wrote that all election should be held under army supervision. It does not matter who wins the election, as long as election is free and fair, it should be acceptable to all, no crying and showing tantrum. 
As for political strength at any place, all have their own belief, until election result, then air comes out of balloon or people start showing hate, accusation and tantrum … and sometime they are right too, as living in Pakistan, rigging is part of election, so one should try their best to ask for free and fair election under military supervision and then keep quite about results.
As for which party is gaining votes, then obvious to me is MQM (maybe I am wrong), because I can see many PPP and ANP top party leaders and members, who also had say in their respective parties, in recent past have joined MQM, especially from Karachi. That includes right hand man of Shahi Syed as well as most important PPP party leader from Karachi Nabeel Gabool.
