No. IK has actually changed the system although not completely but other parties are being forced to make rational choices in terms of economy and people / media are holding their feet to the fire .Now they know that cant lie and make stupid politically statements like they used to do in the past.So if PTI/IK's criticism alone can bring a change in mindset and force the status quo to change themselves for better , thats an accomplishment in itself. Whether he wins election or not , he has brought awareness which no other politician was able to do . So no he is not 12th man, He is probably the player who is not involved in match fixing but is disliked by the team but match fixing team cant throw him out .
