Mandatory voting, what an absurd idea.

If you can't get people to voluntarily participate in democracy then you have a failed implementation of it.

Furthermore, the ability to not vote is a powerful and necessary option, as it's hard for those in power to imply that they have a mandate if <10% of the population actually participated in it.

I don't know what mandatory voting accomplishes except giving those in power the ability to say, "Tut tut! No complaining! You got your vote, after all."
