It's all mixture of jahalat, being bullied, bought out, pressured, blackmailed, and rigging.
As for NA-120, last time in Ayaz Sadiq's by election; 18,500 votes (selected UC) were struck down/transferred and disabled. Margin of official victory was ~3,500.
In this election 29,000 are dubious, while till yesterday final lists of ~12,000 were selected to be disabled. This time disabled/transferred votes will not be more than few hundreds from each UC; to not raise any red flags.
Police Muqabla Chief Architect ex IGP Punjab is spearheading the control rooms setup for this election.
If PTI remains as lax as in bringing voters from home to polling stations like it was in 2013 then result will be only a widened margin of victory for Kulsoom.
Only person in PTI of interior city Lahore who understand constituency/voting politics is Aleem Dar - rest of the other ones like Hammad, Waleed and even Shafqat are too shareef for hooligans of PMLN.
However, the gravity of situation (from $harif's POV) can be partly assessed by the fact that party winning this seat since 25 years, the Chacha had to beg the Bhateja to run the campaign - even then Bhateja flew away in first class to London
And daughter is begging for votes on the basis of her old and ailing mother and not on the "development" of PMLN in its 36 years of cumulative rule in Provincial and Federal level. What a pity!
