if present crisis continues,i dont think elections will be held as scheduled.many think we are heading towards martial-law.
1-and yes we have national as well as provincial election system.
2-i think there are 3 major political parties/alliances...A.R.D,M.M.A and P.M.L-Q plus M.Q.M,besides there are nationalist parties and ofcourse tehrik-e-insaaf.
3-most likely if elections are held at all,there is going to be a split mandate,coz that suits the establishment most.
4-MMA+PML-N+TEHRIK-E-INSAAF
5-ruling party is a cocktail of power hungry politicians,some of them were forced to change their loyalities after the previous elections but a majority willingly joined the band wagon of the dictator.i hate them all
