That occurs to me is perhaps we are seeing a return towrds national parties instead of regional ones. The last election had a stark split between the provinces: PTI in KP, PML(N) in Punjab, PPP and MQM in Sindh and ostensibly PML(N) in Balochistan but in reality a mix of local powers and parties. This time PTI has seats across the country, and PPP has some interest, if not a lot of seats, outside Sindh.
I’m delighted to see that Mohsin Dawar appears to have taken the North Waziristan seat (though I think it’s not official).
