I happened to turn 18 right in time to vote in a [US] presidential election year. I've made a point to vote in every election I can from that point on.
Did I have "a lot going on"? Sure. Do I have utter faith in "The Government" and//or "The Voting Process"? Not really.
But I still vote. It's my right and also, as I've come to see it, my duty. Free speech or no, I believe that if I want to complain about an election and be taken seriously I should participate in it at at least the bare minimal active level.
