Habermas
"Democratic governance rests on the capacity of and opportunity for citizens to engage in enlightened debate". Such engagement needs to happen in an open forum, i.e. a public sphere where the voices of everybody in a democracy can be heard. It is these voices that will ultimately determine how society is driven, how new leadership is elected and how democracy progresses.
I find this to be a fair, though somewhat utopian sentiment. If one observes general elections in India, I would conclude (as a lay person) that the debates about the direction of the country and the world's largest democracy are carried out in the popular (read, cable) media and newspapers, which are read by and participated in by the nation's educated classes. Somehow, the nation's largest section of population that largely lives in the villages and depends on farming for sustenance have not been huge participants of the debate, except perhaps at the regional level. Their needs are not typically addressed in or out of the media, perhaps the reason why India has historically been a developing, rather than a developed country. And yet, the most recent general election was decided based on these marginalized people who live in the villages and countryside, rather than the educated middle classes you strayed from their responsibility to vote.
Some places make progress because of the principles of democratic participation and debate. Others apparently progress in spite of them.
