PML N is facing result of a war between money king of Pakistan and Ch Nisar . I have posted some thing about on a thread about SS and Nisar meeting Kiani but that was closed . About PPP you are 50 % right and that is too result of effort of Zardari to having full personal control on party. I have been on PTI dharna on 14th August this year and have been watching closely all before that , What made it popular after 14th August , It is very easy to know. Establishment have permanent touch with many and they only have to tell them about their ‘Manzoor e Nazar’ . Rest is easy . However there is something els than establishment ,which know better every thing .
