In Cuba, the Communist Party of Cuba is the official state party.
According to the Wikipedia article on the Cuban electoral system,
Candidates for municipal assemblies are nominated on an individual basis at local levels by the local population at nomination assemblies.
The election of municipal assembly delegates involves nomination by voters in nomination assemblies, compilation of posting of candidate biographies, voting by secret ballot, and recall.
How does this work in theory, and how does this work in practice? Are candidates screened by the government, the Party, or otherwise? Or can anybody nominate anyone? According to the Wikipedia article, the Cuban government contends that the Cuban political system is democratic. To what extent can this be confirmed or denied as far as local elections are concerned?
