Anything compulsory is bad.
How do you expect to make sick people and disabled people go vote? How about people who have some serious business that day?
Depending on the election rules, a person who stays home usually doesn't affect the overall outcome of the election. They just remove themselves from the voting body, and have a full right to do so.
The act of not voting is also a vote of sorts.
Plus, it's a politician's job to motivate his electorate to turn up. If you'd remove that you'd make their job much easier.
Also...if I was forced to vote I'd just make my ballot invalid by circling both candidates. You can't force people.
