Should U.S. citizens be forced to vote?:
A vote rule to rein in the free riders, by Peter Singer, Project Syndicate: As an Australian citizen, I voted in the recent federal election there. So did about 95 per cent of registered Australian voters. That figure contrasts markedly with elections in the United States, where the turnout in the 2004 presidential election barely exceeded 60 per cent. In congressional elections that fall in the middle of a president's term, usually fewer than 40 per cent of eligible Americans bother to vote. There is a reason why so many Australians vote. In the 1920s, when voter turnout fell below 60 per cent, parliament made voting compulsory. Since then, despite governments of varying political complexions, there has been no serious attempt to repeal the law, which polls show is supported by about 70 per cent of the population. ...
In practice, what is compulsory is not casting a valid vote, but going to the polling place, having one's name checked off, and putting a ballot paper in the box. The secrecy of the ballot makes it impossible to prevent people writing nonsense on their ballot papers or leaving them blank. While the percentage of invalid votes is a little higher where voting is compulsory, it comes nowhere near offsetting the difference in voter turnout. Compulsory voting is not unique to Australia. Belgium and Argentina introduced it earlier, and it is practised in many other countries, especially in Latin America, although both sanctions and enforcement vary. ...
When voting is voluntary, and the chance that the result will be determined by any single person's vote is extremely low, even the smallest cost -- for example, the time it takes to stroll down to the polling place, wait in line, and cast a ballot -- is sufficient to make voting seem irrational. Yet if many people follow this line of reasoning, and do not vote, a minority of the population can determine a country's future, leaving a discontented majority. ...
If we don't want a small minority to determine our government, we will favour a high turnout. Yet, since our own vote makes such a tiny contribution to the outcome, each of us still faces the temptation to get a free ride, not bothering to vote while hoping that enough other people will vote to keep democracy robust and to elect a government that is responsive to the views of a majority of citizens.
But there are many possible reasons for voting. Some people vote because they enjoy it... Others are motivated by a sense of civic duty that does not assess the rationality of voting in terms of the possible impact of one's own ballot.
Still others might vote not because they imagine that they will determine the outcome of the election, but because, like football fans, they want to cheer their team on. They may vote because if they don't, they will be in no position to complain if they don't like the government that is elected. Or they may calculate that while the chances of their determining the outcome are only one in several million, the result is of such importance that even that tiny chance is enough to outweigh the minor inconveniences of voting.
If these considerations fail to get people to the polls, however, compulsory voting is one way of overcoming the free-rider problem. The small cost imposed on not voting makes it rational for everyone to vote and at the same time establishes a social norm of voting.
Australians want to be coerced into voting. They are happy to vote, knowing that everyone else is voting, too. Countries worried about low voter turnout would do well to consider their compulsory model.
As much as I'd like to see turnout go up, I can't support compulsory voting. It's not because of any worry that voters will be uninformed, irrational, or anything like that, it's more that it seems like an impingement on freedom.
