Practice makes perfect..
I don't think that Vijay will become the CM. Tamil people always want either DMK or ADMK no matter who is there in the seat.
After Jayalalitha we cannot say who will become the leader. But after Karunanidi there is a list of people it can be Stalin, Azhagiri, Dayanidi, even Kanimozhi. Though we know nobody is worth to become the Chief Minister the Tamil people wants someone from the family of Karuna. If Jayalalitha has got any son or daughter then he or she is also capable.
Yes the only quality is from any political family background. We cannot expect another Kamaraj or Annadurai.
