These are tough days for voters. Specially for those that believe in the folk theory of democracy -people vote according to their preferences, and governments act according to their ideological foundations. It's a good moment to retrieve the rationale for voting and I pick three statements from a book:
In the conventional view, democracy begins with the voters. Ordinary people have preferences about what their government should do. They choose leaders who will do those things, or they enact their preferences directly in referendums. In either case, what the majority wants becomes government policy— a highly attractive prospect in light of most human experience with governments. Democracy makes the people the rulers, and legitimacy derives from their consent.
Unfortunately, while the folk theory of democracy has flourished as an ideal, its credibility has been severely undercut by a growing body of scientific evidence presenting a different and considerably darker view of democratic politics. That evidence demonstrates that the great majority of citizens pay little attention to politics. At election time, they are swayed by how they feel about “the nature of the times,” especially the current state of the economy, and by political loyalties typically acquired in childhood.
We will argue that voters, even the most informed voters, typically make choices not on the basis of policy preferences or ideology, but on the basis of who they are— their social identities. In turn, those social identities shape how they think, what they think, and where they belong in the party system. But if voting behavior primarily reflects and reinforces voters’ social loyalties, it is a mistake to suppose that elections result in popular control of public policy. Thus, our approach makes a sharp break with conventional thinking. The result may not be very comfortable or comforting. Nonetheless, we believe that a democratic theory worthy of serious social influence must engage with the findings of modern social science.I agree absolutely with this view. A highly-recommendable book.
