And I recall there was a problem with term limits, namely lack there of, which a democracy should have to ensure a good turn over of leadership.

This is a problem with using terms that are relatively vague like "Democracy." If term limits for the chief executive are required, then the USA would not be considered a democracy until the early 1950s (or if a complete enfranchisement is required, then the 1960s). The point is that democracy is a broad term, and as Marx pointed out in even his early works: it's necessary to distinguish between formal and actual democracy, between existing bourgeois democracy and a potential working class democracy.

For example I would say that Cuba is a democracy despite the lack of formal votes for the executive. It's just not a democracy in the same sense that the United States is a democracy.

Those are fair points. Literally, Democracy just means rule by citizens/people in Greek, so a system which only counts men as citizens (or people) but lets them all vote would technically be a democracy. I do not mean that without term limits you cannot have a democracy, I simply mean they are a good way to try and combat over concentration of power into one person.
But actually, neither the US or Cuba is a democracy, they are both Republics. In true democracies the people vote directly on matters of political importance. That was what the ancient Greeks did, mainly by shouting or orating to a crowd on the issue and then putting it to a vote.
