Voters will choose the leader they think will do the best job, if this is the incumbent then that is democracy. Election machines and lobby groups may be able to help an incumbent somewhat, but at the end of the day the leader must be able to convince the people that he has done a good job and is still suitable to lead. As to the issue of countries like Zimbabwe, if the people want to keep electing a revolutionary hero, that is their choice. The overruling of election results, as occurred in the most recent Zimbabwean election, however, is not democratic and thus unacceptable for a mature state. Mugabe’s ability to flaunt the will of the people was not due to a lack of term limits, however, but on an inadequate separation of powers inherent in the system. [1] Adding term limits to that system, and indeed any system, will do little to redress imbalances between branches of government. The case of Vladimir Putin is similarly instructive, despite stepping down after his second term, he thereafter took the office of Prime Minister and maintained effective power. Term limits are no barrier to those determined and popular enough to hang on to power.  [1] Jones, Charles and Bruce MacLaury. 1994. The Presidency in a Separated System.
