IK's support is often claimed to be widespread, but somehow it never translates into that in reality. If enough people do actually come out and show their support for IK to the extent that it is claimed, no one can keep him in jail, no matter what.
majority of them are mu kai fire, they can tweet, youtube and insta (where they earn money with click bait thumbnails lying through every bodily opening), i would like to see the likes of shahbaz gill, imran riaz, adil raja and others to come back and fight instead of encouraging kids of others to go out and be in trouble.
PTI is modified version of MQM with the difference is that former had real street power with thugs while the later have cyber bullies.
Mind you, both the parties have decent royal followers who don't indulge in anything wrong but are given a bad name courtesy of leadership and certain bad thugs
