Dear,
Ours is a country where the basic element of parliamentry democracy,well educated electorate,is very rare if at all,and that too,due to our local ethos fail to vote on merit.I have personally heared of youngs telling to vote for PTI but at eleventh hour not to do so,because.
1)The candidate is already going to fail,then why to waste vote.
2)there is no chances of PTI to win overwhilming majority,so why not vote the likes to constitute majority and so earn there favours.
Similarly one may count many cases,
So it will take the time though change is taking place.
