Nitish has shown that he is a successful politician and a better administrator. He has to be the next CM and is in a position to improve his image further,qualifying for India's P.M. All these old politicians with archaic ideas are like the 'Empty asafoetida' container with nothing inside but the smell of asafoetida. Let them give way for young, energetic, enthusiastic politicians interested in developmental politics.

Perhaps thiscannot be generalized.It depends on each individual.ManmohanSingh is highly qualified but acts only as a puppet of Sonia Gandhi.We cannot expect much from Advani.Though Nitish Kumar has shown excellent qualities.
