Most people are not interested in politics, that's why you can call them sheep. But sometimes there is an election, that's the only time when they are interested to hear about politics. So elections are important, not because of the outcome, but because at every election there are some people listening about how they are governed and some of them are waking up. People who don't participate make sheep think that it is not important, nothing to see here and nothing to think about. That's exactly what the elitists want: people who don't care.
