Because the split is required for governance purpose only. There is no particular regional, lingual, ethnic feelings, in fact, it will be very difficult to draw a line between east and west. Almost everyone feels there that state needs an administrative division for better governance and development but this comes only during political or intellectual discussion.
I have to differ with u mama, A.P was doing good and was among the top performing states. It is the votebank politics of congress that led to disturbances in the state and the rise of the call for seperate statehood by T-people..
