Lol could've gone for more. 30 seats in punjab, none in Baluchistan I think and 4 in sindh doesn't give any. Only National Assembly was other choice.
It's funny how KPK is not rigged election and senate elections can happen there but not other parts.
Perhaps you'll get 7 more seats in next election, that's 14 seats. When you win 2018 elections, good luck passing laws through senate until 2021 senate elections (even then you likely won't get enough seats and wait till 2024, just as PMLn despite majority in parliament and punjab has to wait till 2018 to be major party in senate.
Think about long term, not short term. Those National Assembly seats and maybe one from punjab with alliance could play a huge role in future. Nawaz lost in 1990s from becoming Amin u moumenin because of 1-3 seats.
