Who is best among them?.I think is mwl.J.K.Nyerere on kilimo as majority of Tzs live by dependng on it.Then who is worst? I thnk the 2nd J.K back to N as he spends most of his time travels abroad surveying for nothing while his voters live poor life with abudant natural resources and human resources,and the economy of his country is droping drastically unreasonably!.We need m4c to rescue the catastrophy!.
