NADRA has declared that 93,852 voters in NA-122 cannot be verified. Isn`t this the time to decide that the subsequent elections in the country, whether of local government or at national level, should be on a biometric system? Why not try a by-election on the biometric system? It will solve the rigging problem in the electoral system. If 80m SIMs can be verified in 15 days biometrically, why can`t the polls be conducted using the same system? Yaaser Rwalpindi
