Iranian Election

In a couple of weeks Islamic Republic in Iran will hold an "election" for the selection of the members of the Parliament and the Assembly of Experts. What these political bodies are is not really relevant as I will explain in a moment. So far the majority of the candidates for these two assemblies have been disqualified through a non transparent process. Qualified candidates are chosen by the status quo for the purpose of maintaining the rule of the existing clique of clergies and their tight circles of beneficiaries. Open discussion of issues and criticism of the system is suppressed by detention, long term imprisonment and death. Meanwhile the Islamic regime spends plenty of resources to convince the population that they should participate and cast their ballots, portraying the people's participation as "patriotic", "anti-enemy" and "anti-imperialist". Should one participate in this election? Is there any principles one could adopt or follow?
