Well no real impact I guess. It's been known for a long time that the father likes Stalin and has been maneuvering him for top job (I've heard stalin is the degenerate one by the way). So the natural power base for Alagiri was limited in comparison to Stalin. This will be seen as the last tantrum by Alagiri- only officially confirming what has been known for so long- that stalin will 'inherit'. But there is a deeper trend here. People of TN have generally been smart- they keep switching the parties one after the other. But this time there is a real wave against DMK. I think Karuna has missed a changing voter-scape there. JJ, who was once famous for her corruption has not invited similar news this time around. I think DMK will erode, stalin will find it difficult to turn it around and AIADMK will remain strong for some time.
