Who told you that PML(N) got highest votes in PA (even assuming that when you refer to PA, it means Punjab provincial assembly as you do not see beyond Punjab). If you have any reference, why not show that? 
As for PML(Q) votes, they did not only got highest votes but many of their votes fell to independent candidates like Wattoo as even though he is VP in PML(Q), he contested election as independent (and there are many such PML(Q) candidates who contested election as independent). As for Wattoo, he is still office holder of PML(Q) and did not resigned from the party.
