Why is cuba a non democratic country?

Answer 1

Cuba is run under a system which they call "Party-led Deomcracy". While elections are held, one must be a part of the "Communist Party" to participate. Opposition candidates are allowed and often win, but not Opposition parties. Thus, while they government is in theory responsive to the will of the people, they have also ensured that they can never be Democractically taken out of power.

I would however be remiss if I didn't point out that even with a "party-led Democracy", which many would contend is not a democracy at all, they have a higher voluntary participaton rate in their elections than America does.

Also, Castro was not chosen by the people, he was chosen by a politburo chosen by a Congress chosen by the people. Of course, in the US we don't elect the president, we elect the people who will go vote for the president (elector system) provided that they choose a candidate prescreened by a national party.

Answer 2

Because the government is (or was) run by the dictates of a single individual who retains power through control of the military, and does not allow any organized opposition.
