That's true.. PTI seats can only increase in Karachi.. not decrease.. that's why nooni want PTI to fail and do not meet expectations..
Good thing is that Karachiites are educated enough to understand the federal/ provincial administrative responsibilities issues, and may not leave PTI even if PTI is not able to do much..
Remember I told you that Karachi belongs to PTI.. you always asked this question, but I always said that.. because all my family, extended family, my friends, friends' friends.. all were PTI supporters.. (except very very few)..
And let me tell you, they aren't changing their vote anytime soon.. in fact, in next elections, more people will enter voting age, and I see at least 18 seats for PTI from Karachi..
