No one in pakistan ever imagined that they will be able to get rid of two main parties in the country, despite knowing for a fact that they were corrupt. The main reason I think was the electables, they would get elected each times and then switch sides, depending on who was likely to make government. even today PMLN and PPP are following the same strategy. I wonder no body is surprised that we never see a new face in government, same people rotating turn..Aaj meree baaree, kal teree, and smaller parties like JUI are equally responsible for this mess. no one made a serious and sincere effort to change the system until Imran Khan..for the first time we have a real alternative and Inshallah we will throw them out. Its the beginning of a new Pakistan.
