The difference between rest and PTI is that may be IK is not corrupt himself and has a better international standing.
The rest, they are the same faces with different names. They should all just somehow die at the same time (preferably today), if Pakistan is ever to see any change and progress.
By the way there is one possibility though ........... if he is able to demonstrate street power in really huge numbers, in next election he may very well come back with 2/3 majority. That will be interesting.
