How do you know he has no knowledge of current affirs?? when you and me can have knowldge what makes you think he dosnt?? And he is not a fool. Dont you think he must have alrady thought about everything befoe making a decision to enter politics.
And regarding his duaghters an brother, people will be more concerned about their issues than about his daughters.
And i am not saying he will straight away become CM, which is difficult, but he will make an impact cos people are sick of congress govt.
