But voting isn't just about getting the best guy in. It's also about keeping the worst guy out.
I could rant for hours about the insanity that is the American electoral system, but it seems to me that one of the most consistent problems is voter apathy.
People are always complaining about what the government's doing or not doing, but how many of them are actually registering those complaints in the one way that actually matters to politicians - in the form of a vote against them? And yeah, you can say that all politicians are corrupt anyway, and that your one vote isn't going to make a difference, but you know what? That kind of talk is just self-defeating. Because by not voting, you're in essence ensuring the continuance of that corruption. You're letting them get away with it.
But consider this: If enough people consistently took a stand against a candidate's policies by voting for the other guy, wouldn't that candidate be forced to reconsider those policies in order to regain the favour of the electorate?
And when it really boils down to it, it's not that big an ask of citizens. So you take a bit of time out of your day once every couple of years. You get some information about the candidates, you head over to the local polling station and you cast a vote. Worst case scenario? You've wasted an hour of your day. Big deal. But sometimes, even a small number of votes can mean everything.
