Opposition to extremism has not been an election issue upto now, the stance taken by political parties are their own and not reflective of the opinions of people voting for them. Just to remind you that the only political party that used the issue of fight with Taleban in election campagn was ANP, which at that point was saying that theu will make a truce with taleban and stop bloodshed of Pakhtoons.
