Widespread voter ignorance is not primarily the result of stupidity, lack of education, or lack of information. If it were, political knowledge levels should have increased substantially over the last few decades, as IQ scores, education levels, and the ready availability of information all went up. In reality, most political ignorance is probably the result of rational behavior by individual citizens. It makes little sense to spend a lot of time studying political issues when the chance that your vote will make a difference is infinitesimally small.
