But Carina Tertsakian, the Rwanda researcher for Human Rights Watch, said she sees Kagame's record as mixed.
"There have been real improvements (in Rwanda) in terms of development, in terms of access to public services, but in terms of respect for civil and political rights there are still really serious concerns," Tertsakian
expects a yes vote on Friday but questions whether this might be influenced by restrictions on political rights.
Several opposition leaders and activists are currently in jail in Rwanda, and in recent years there have been attacks on opponents and critics of the government.
There have been some signs of a freer media lately, Tertsakian
said with radio stations airing discussions on the referendum, for example.
