A golden era in Democracy?

Democracy is supposed to be all good. A country that has a democratically elected govt is supposed to be more elite than countries with any other forms of government. But think again, can there be a golden era with superb governance in a democracy? Will the opposition party allow this to happen, when it diminishes their chances at coming to power in the next election? Democracy cannot succeed if a different group of people has good reasons to undermine the current government. Perhaps democracy works better if individuals instead of parties get elected.
