In U.S. presidential elections over the past few decades, about 55–65 percent of voting-age citizens actually voted, according to the U.S. Census. In congressional elections when there is no presidential race, or in local elections, the turnout is typically lower, often less than half of eligible voters. In other countries, the share of adults who vote is often higher. For example, in national elections since the 1980s in Germany, Spain, and France, about 75–80 percent of those of voting age cast ballots. Even this total falls well short of 100 percent. Some countries have laws that require voting: among them, Australia, Belgium, Italy, Greece, Turkey, Singapore, and most Latin American nations. At the time the United States was founded, voting was mandatory in Virginia, Maryland, Delaware, and Georgia. Even if the law requires people to vote, however, no law can require that each voter cast an informed or a thoughtful vote. Moreover, in the United States (and in most countries around the world), the freedom to vote has also typically meant the freedom to not vote.

Why do people not vote? Perhaps they do not care too much about who wins, or they are uninformed about who is running, or they do not believe their vote will matter or change their lives in any way. Indeed, these reasons are probably tied together, because people who do not believe their vote matters will not bother to become informed or care who wins. Economists have suggested why a utility-maximizing person might rationally decide not to vote or not to become informed about the election. While a few elections in very small towns may be decided by a single vote, in most elections of any size, the margin of victory is measured in hundreds, thousands, or even millions of votes. A rational voter will recognize that one vote is extremely unlikely to make a difference. This theory of rational ignorance holds that people will not vote if the costs of becoming informed and voting are too high, or they feel their vote will not be decisive in the election.

In a 1957 work, An Economic Theory of Democracy, the economist Anthony Downs stated the problem this way: “It seems probable that for a great many citizens in a democracy, rational behavior excludes any investment whatever in political information per se. No matter how significant a difference between parties is revealed to the rational citizen by his free information, or how uncertain he is about which party to support, he realizes that his vote has almost no chance of influencing the outcome … He will not even utilize all the free information available, since assimilating it takes time.” In his classic 1948 novel Walden Two, the psychologist B. F. Skinner puts the issue even more succinctly via one of his characters, who states: “The chance that one man’s vote will decide the issue in a national election … is less than the chance that he will be killed on his way to the polls.” The following Clear It Up feature explores another aspect of the election process: spending.

While many U.S. adults do not bother to vote in presidential elections, more than half do. What motivates them? Research on voting behavior has shown that people who are more settled or more connected to society tend to vote more frequently. According to the Washington Post (2012), more married people vote than single people. Those with a job vote more than the unemployed. Those who have lived longer in a neighborhood are more likely to vote than newcomers. Those who report that they know their neighbors and talk to them are more likely to vote than socially isolated people. Those with a higher income and level of education are also more likely to vote. These factors suggest that politicians are likely to focus more on the interests of married, employed, well-educated people with at least a middle-class level of income than on the interests of other groups. For example, those who vote may tend to be more supportive of financial assistance for the two-year and four-year colleges they expect their children to attend than they are of medical care or public school education aimed at families of the poor and unemployed.

A number of proposals have been offered to encourage greater voter turnout: making it easier to register to vote, keeping the polls open for more hours, or even moving the election day to the weekend, when fewer people need to worry about jobs or school commitments. However, the changes that have been made do not seem to have caused a long-term upward trend in the number of people voting. After all, casting an informed vote will always impose some costs of time and energy. It is not clear how to strengthen people’s feeling of connectedness to society in a way that will lead to a substantial increase in voter turnout. Without greater voter turnout, however, politicians elected by the votes of 60 percent or fewer of the population may not enact economic policy in the best interests of 100 percent of the population. Meanwhile, countering a long trend toward making voting easier, many states have recently erected new voting laws that critics say are actually barriers to voting. States have passed laws that reduce early voting and restrict groups who organize get-out-the-vote efforts, and have enacted strict photo ID laws, as well as laws that require showing proof of U.S. citizenship. The ACLU argues that while these laws profess to prevent voter fraud, they are, in effect, making it harder for individuals to cast their vote.
