 It's election day in Rwanda, but there isn't much doubt about who will win the presidential contest. The incumbent, Paul Kagame, has been in power since 1994. He's won the past three elections with landslide victories, more than 90 percent of the vote. Kagame's 30 years in power have shaped Rwanda in profound ways, as Michela Rong has reported. She says it's important to remember the circumstances when Kagame first came to power in the 90s.
