Re: PTI’s Tareen trounces PML-N’s Baloch in NA-154 Lodhran by-poll
You are over simplifying it. 2+2 is never 4 in politics especially in South Asian politics where ethnic, religious and bradaree loyalties swing votes like hell.
At times you actually lose votes by making alliances. Recent example of PTI + JI alliance in Karachi. I still believe those two parties would have fetched the same result (if not better) without alliance.
