Well that's cheating
Which isn't to say it's not a good idea, because I think it is
We certainly could use that for some of the more EU-centric elections around here where fully a third of the population just doesn't give enough of a damn to spend the 15-45 minutes it takes to get to the voting station, vote, and get back home.
Yeah, because forcing someone to do what they don't want to do in the first place not only is good for peoples' rights (and yes, people have a right to sit around and do nothing with their life if they want to), but it obviously creates a true representation of the people's political opinion.
Slate.com: What if voting were mandatory?
Australia also has a much higher rate of spoiled ballots than nearly any other democracy. There were 500,000 such ballots (out of 10 million cast) in this month's (October 2004) election. These include protest votes and those cast by recent immigrants who were confused by the notoriously complicated ballots. It does not include "donkey votes," so named because apathetic voters play pin the tail on the donkey at the polling station, randomly making their selections.
Now, programs to get people interested in voting
and politically informed (you have to have both, otherwise you'll have people really excited to push a button, but have no clue why they're pushing that button other than for ****s and giggles) are perfectly alright. I went through one of those programs my senior year in high school, so I
know that they work.
