You can still spoil your vote and lodge a protest vote but you must at least turn up and be counted as having voted.
Wouldn't agree with that at all. I don't vote in elections anymore, only in referendums because Smurf that's really the only time that your vote makes an actual tangible difference that you as an individual can measure. That's really the only time that democracy becomes a reality. The rest of the time it's an illusion.
Now I agree that democracy despite its flaws is the best system we've come up with but the bottom line is that all you get with your vote is the chance to give a particular party the power to run the country. After that they can do whatever they like and deliver or fail to deliver on their election promises etc. and there's sod all you can do to remove them from the position of power you gave them until the next election rolls around. And in the end, we all muddle along anyway.
