It may be not that easy. Just getting people's support is not enough for a political party to make a government in Pakistan's democracy. :-)
Do you remember how PPP made the government in 2008? They didn't win in Punjab. They had enough seats in Punjab to make the government. PMLN will struggle to get seats from outside punjab. I agree they will be a majority party in Punjab.
The establishment will never allow a party to govern which is openly mouthing against them. Also, PTI has chosen to put only one party's members behind bars. (i.e. PMLN) It means if PMLN comes to power then most of the PTI members will be in Jail in two years. So how can the establishment and PTI stop PMLN getting into power in two years?
The only solution is, if PPP and PTI align then they may get enough votes to make the government. It wouldn't matter if PMLN gets majority votes like the 2018 elections. At most Shahbaz Sharif will become Chief Minister of Punjab again. Imran Khan will continue as the PM, Zardari may again become the president. Don't worry about what Imran Khan says about Zardari today. He had also called Pervaiz Ilahai Punjab kah sab say barha daakoo, then asked him to be the speaker of the Punjab assembly. He also hated MQM before, but now says that MQM politics is similar to PTI.
This is the reason Maryam Nawaz is calling Bilawal selected because it looks obvious that there has been a deal between the establishment and PPP. There is no other possibility to stop PMLN from coming into power in the next election.
Shehbaz-led PMLN, with Ch Nisar as its key member, will have no issue in working with Military. Nawaz and Maryam too will compromise ( At minimum, they will stop attacking Military )when their party will come into power. This is how our political parties work.
Now, let’s look at some number-crunching from Punjab for the past three elections. PPP was able to form government in Centre in 2008 because it came very close to PMLN in Punjab. PMLN won 63 NA seats while PPP won 51 seats. In 2013 elections, PMLN won 126 seats, PPP won ZERO. PTI got 8 while 14 seats were won by independents. In 2018 elections, PMLN won 60 seats, PTI won 67 while PPP won 6 seats.
Due to the reasons mentioned in my previous post, PTI will suffer badly in Punjab. As a result, PPP might gain few seats from South Punjab and that’s it. The real gainer will be PMLN who could win close to 120 seats from Punjab alone, close to what they got in 2013. Add to it another 6 or 7seats from Hazara Division of KP ( Haripur, Abbotabad, Mansehra), one or two from Capital territory, and the party will be close to forming government in Islamabad. One needs 137 General seats ( out of a total of 272 seats ) to form a government in Pakistan. Reserved seats are granted in proportion to general seats. So, if you win 137 General seats, your tally becomes 172 after adding reserved seats.
So, my analysis is that PMLN will form governments in both Centre and Punjab, PTI in KP, PPP in Sindh, and BAP+JUI in Balochistan. Shehbaz-led PMLN will pose no threat to Military’s hegemony. Mariam will be nurtured for a possible turn as CM Punjab in 2028.
