I was perusing "Today I Learned" on Reddit and saw that Australia and much of South American has compulsory voting -- making it illegal not to vote in elections.
Clicking on the link, I see even more countries that do that.
Compulsory voting may encourage voters to research the candidates' political positions more thoroughly. Since they are voting anyway they may take more of an interest into the nature of the politicians they may vote for, rather than simply opting out. This means candidates need to appeal to a more general audience, rather than a small section of the community.
If voters do not want to support any given choice, they may cast spoilt votes or blank votes. According to compulsory voting supporters, this is preferred to not voting at all because it ensures there is no possibility that the person has been intimidated or prevented from voting should they wish. In certain jurisdictions, voters also have the option to vote none of the above if they do not support any of the candidates to indicate clear dissatisfaction with the candidate list rather than simple apathy at the whole process.
I think being an informed, involved citizen is vital to maintain our Republic. If you are lazy and wish others to do the work for you, fine. Pay for the "privilege". Give people who vote a tax credit.
Compulsory voting. Now there is a definition of freedom. Simply stupid. If you have no idea of who you are voting for what good is it to have such a vote cast? I fail to see the logic in this at all. What is more important, making a wise choice or having a high vote count?
