Please make the effort to go and vote, good men and women have died for it. If you don't want to vote for any of the candidates, simply write "none of the above" at the bottom of your ballot paper, they are all counted, you won't get in any trouble, and if enough people did this perhaps politicians might realise they are on the wrong tack. Doing this at least proves you aren't apathetic about elections, but just can't elect any of the available candidates. I remember this from my old college days, when we were given a short lecture by our local returning officer, he made us realise that if everyone who didn't actually vote registered a protest, notice would be taken of it.
