The reality is that democracy is a very blunt instrument, and in today’s environment we are choosing between ways of muddling through. We may hear that the election is about different visions for America’s future, but the pitches may be more akin to selling different brands of soap.
We hear so many superficial messages precisely because most American voters have neither the knowledge nor the commitment to evaluate the pronouncements of politicians on economic issues. It is no accident that the most influential political science book of the last year has been “The Myth of the Rational Voter,” by Bryan Caplan. The book shows that many voters are ill-informed or even irrational; many economic issues are complex, and each voter knows that he or she will not determine the final outcome.
Rather than being cynics, we should be realists. Democracy is reasonably good at some things: pushing scoundrels out of office, checking their worst excesses by requiring openness, and simply giving large numbers of people the feeling of having a voice. Democracy is not nearly as good at others: holding politicians accountable for their economic promises or translating the preferences of intellectuals into public policy.

PS. I guess you've started reading Bryan Caplan's book by now ( I mentioned it before, e.g., here or here). If not, hurry up, what are you waiting for?! :-).
