Maybe Karachi overall has some PTI in it but still its at immature level because if he had any Real Public Support then Karachi would have been center of Electoral reform and JC campaign irrespective of all the pressure from MQM. Karachi is not a city as it is perceived from outside it has More Activism then any other city in Pakistan even in the past Karachiite have shown RESTRAIN in worse situations like during Fatima Jinnah's Election and also during 1992 Military Operation against MQM.public support in terms of majority, no not at all. in terms of na-246, id say mqm has just enough votes to win the election, not more. and where did i say pti does not have public support? and how do you know pti brought people from all over the city and not na246? check my originals post again and the picture attached to it, and come and talk if you have some concrete knowledge based on 'ground realities'.
SO if people are not coming out for Imran Khan then he should look into his Weakness of his own Party rather then Accusing MQM for everything. If MQM stay non progressive they would die their own death like JI but if they are tried killed then they would Bounce back with even more strength to sphere.
