2.            p.128 Compare the Brazilian case with box above on one party regime in Tanzania. What common elements and what differences do you see?  Does it make sense to think of them both as modernizing authoritarian?

3.            p.131 What elements of neopatrimonial authority to you see in Abacha’s regime? How do you think a country can best begin to move away from this type of rule?
