I have been bashed a lot by PTI supporters for saying this (what's with you guys, hear other's point of view too please) but i think PTI has made a lot of promises and have a lot to prove, I personally think they were delibrately let to win KPK one of the hardest province to manage right now, just so they can screw up and be proven wrong.
PTI reminds me of early days of MQM to be very honest (trust me i have seen MQM in 80's and 90's and living in F.B.Area i know a thing or two about their public support at that time) all the excitement, young blood, enthusiasm ... everything just reminds me of MQM ....
Till now as far as Karachi is concerned only MQM have made efforts to improve it, PPP never bothered, PML(N) never bothered the only real development we saw here was under Musharaf era when MQM was given a free hand. MQM do have potential but unfortunately due to their last five years (specially) policies, turns etc have lost a lot of ground politically, like it or not.
If PML(N) have made a lot of promises lets see what they deliver, 350mw cut from KESC, the budget, everything till now points in the wrong direction though.
