There is difference between keep voting for Shareef and Bhutto family with out having any alternate option and giving tickets to electables (which should have to be discourage), after IK PTI will not be led by his offspring. By that standard, Imran Khan can never make Pakistan corruption free country. His 90% party members are corrupt and have remained in scandals.
Apart from PTI, PPP also claims to bring workers in the mainstream politics but we all know who eventually makes it to the assembly Ignore mainstream pol parties for a second, we find small pol parties comprising wholly of workers running for assembly. How many of them make it?
And then, there’s good ol’ paradox of experience vs employability. Even, if parties choose loyal workers to contest election, equip them with resources & finances, but a common worker severely lacks interpersonal skills that’s needed in a constituency to turn support into vote.
