McClatchy has a good article on the human toll in Zimbabwe and the probable reasons for Mugabe's resurgence through using violence and intimidation. The main reason- the hardliner former "freedom fighters" from Zimbabwe's independence struggles in the seventies and eighties who still retain a lot of power in Mugabe's ZANU-PF ruling party and the armed forces. Former ZANU-PF high-ranker and presidential contender Simba Makoni also lost substantial support because of these hardliners. This makes a lot of sense because in reality, oppressive regimes are often more than just the work and actions of one man and Zimbabwe is no different. As notorious and infamous as Mugabe is, he alone cannot be held responsible for Zimbabwe's failings and oppression. Kind of similar with the US where George W. despite the widespread amount of loathing for him, also cannot be solely blamed for all America's actions under his rule.
