Well, PTI has a problem. It is not acting up as a party which believes in parliamentary system . In parliamentary democracy , the ruling party must collaborate and work with opposition to benefit the citizens . The system will stall if both side of the parliament won't work together.
If PTI thinks that EVM is the best answer, they will have to work with opposition to change the electoral system of the country. It can't be done all alone.
in 2018, the boots were active and very active. I have seen and met ISI operators in Karachi who were there and brought people from Baluchistan to set an agenda for election prior to the election . I am an eye witness myself and I can say it on oath. It was planned during the interim admin time when those who were in charge laid down in front of army planner and generals.
