Clearly PTI is including electables which they ignored it in 2013 and end up loosing the elections by a fair margin. People may object it because of mufaad parust elements like ZM, but it is a smart move because this is how you win elections in Pakistan. People in Pakistan, especially in rural areas, sees the name rather than his work.
Than forget PTI wining elections in Pakistan for ever. You need to understand the psyche of Pakistani voters and the dynamics. Pakistani electoral system unfortunately is based on personalities and name rather than merit. If IK has to win elections of 2018, he has to do lots of compromises here and there.
