Why not? This poster you shared, why can't it be distributed on whatsapp? on social media, pasted on walls, handed out in markets, handed out at Jummah?
At election time they can paste these sorts of posters everywhere...
In the UK we get leaflets through our door with regular updates of policy decisions and actions by our local political parties.
If I was a PTI politician or candidate, i'd have printed tens of thousands of such posters and handed them out door to door. I would have had workers running surgeries after Jummah and at kids schools telling people how to access it. I would milk it for everything it is worth.
Look at the previous examples, BISP, Laptop schemes - all gimmicks. Most people assume this is another gimmick and only PTI loyalists will get these cards. Most opposition leaders will be telling people the videos we've seen are of paid actors. You have to do the ground level work to connect with the electorate.
That's great news. I would still say that to get to the dumbass grasssroots of opposition, a door to door style approach would benefit.
