A right to democracy?

For my research paper I'm going to write about the right to democracy. Article 21 of the UDHR outlines a right to political participation but there is some debate about whether or not there is really a right to democracy. So far in my research I have found that democracy promotes peace and encourages politicians to uphold human rights. Also democracies tend to have less violence. Since there is a human right to peace and security it seems clear that there is at least a connection between democracy and human rights. The question seems to be whether democracy simply promotes and protects human rights or if it is itself a human right. To answer this I think it needs to be known whether democracy is necessary to best uphold human rights, such as the right to peace and security, or if it is just one of a few scenarios in which these rights can be achieved. If peace, human rights, and democracy are all interlinked and dependent upon one another, than it would seem that democracy would be itself a necessity in human rights. If it is the only way to grant people peace and security and people have a right to these, than it would seem that it too was a human right. Does democracy embody a human right? does it just serve to protect them? Is it just a means to achieve them?
