Nice. and it's 50 years not 25. You still have to count Nyerere's time. Even though he did some great things for our country he was still part of CCM. So CCM has been in power since independence.
Korea went from being as poor as us to being among the top 10 economies in that 50 years. We went the opposite direction, becoming one of the poorest countries in the world. Yet people still vote for CCM, expecting something different. The height of madness is doing the same thing over and over and expecting different results.
