While I believe compulsory voting (or compulsory turning-up-at-the-ballot-box as it is here in Australia; what you write on the ballot paper is your business) is more harmful than the voluntary alternative because it forcefully engages people who shouldn't be allowed anywhere near the electoral process, I'd settle for "none of the above" as an option on ballot papers. At least it gives a legitimate outlet for people who feel that way, instead of forcing them to vote informally and have their feelings get lost in that statistic.
