Voter Registration in the United States
States generally require people registering to vote to provide some form of identification to verify their identity and eligibility. The National Voter Registration Act of 1993 made it easier for people to register to vote. Under this law, all states accept the National Mail Voter Registration Form, which can be downloaded and mailed in. In addition, people can register in government offices, such as the state department of motor vehicles, armed forces recruiting offices, and some offices that provide benefits, such as food stamps. In more than two-thirds of the states and the District of Columbia, voters can register online. People who move or legally change their name need to update their voter registration to maintain their ability to vote. Those who change states need to register in the new state and should cancel their old voter registration. In many states, people can declare a party identification when they register or declare themselves as independents. Registering for a party is not a legal requirement for voting, but it can be a requirement to vote in a party's closed primary in that state. Any registered voter can vote for any candidate in any general election, regardless of party affiliation.
The American practice of requiring voters to register is unusual among traditional democracies around the world. In many countries registration is automatic, and records are maintained by the national government and shared with local authorities. Some countries, such as Germany and Australia, call on individuals to register but require registration of all eligible voters; people cannot choose not to register, as in the United States. Voter registration is much higher in countries with automatic or easier registration processes. In the United States an estimated one-quarter to one-third of eligible voters are not registered to vote. In comparison, registration rates in Canada, the United Kingdom, and Sweden exceed 90 percent.
Factors Affecting Voter Turnout
There are also gender differences in voting behavior, with women more likely to vote than men. College graduates are much more likely to vote than people with only a high school diploma. As income rises, the likelihood that a person will vote also continues to rise. Persons with higher incomes are more likely to vote than persons with lower incomes. Non-Hispanic whites are more likely to vote than ethnic minorities.
Rules and procedures of American elections can also help explain why turnout is lower in the United States than in other countries. First, Americans have the opportunity to vote far more often for far more offices than in most democracies. Americans can vote for officials from the town tax collector to the county sheriff to state judges to the president—in some cases in both primary elections and general elections. The plethora of elections provides many occasions for voters to stay home. Voting in the United States is not compulsory as it is in some other countries. Turnout in Australia, where voting is required by law, was at a historic low of 91 percent in 2016. American elections are generally held in the middle of the week, whereas other countries hold them on weekends. Some countries even make election day a holiday. These rules make it easier for working people to vote. The number of noncompetitive races in the United States, particularly for Congress, can also suppress turnout and may contribute to the much lower turnout in midterms than in presidential elections.
States have taken steps to make voting easier. More than half of U.S. states allow voters to cast ballots online, by e-mail, or by fax. More than half allow early voting. While all states allow voters to cast absentee ballots by mail, around 20 require voters to give a reason for this method of voting—and more than two dozen require no reason. Three states—Colorado, Oregon, and Washington—mail ballots to every single registered voter. Those voters simply need to mark their ballots and mail them back.
How Voters Decide
Party Identification from 1972 to 2012
Economic issues also influence how people vote. Voters tend to reward the party in power if the economy is doing well but tend to reward the opposing party if the economy is doing poorly. Voters who believe that less regulation of business and lower taxes create a better economy will likely vote for the Republican candidate. Voters who believe that business regulations are necessary and that the tax system should be progressive will likely vote for the Democratic candidate.
Specific policy issues—especially social ones—also influence voters. For example, many people strongly identify themselves as pro-life (in favor of limits to or an outright ban on abortions), while others strongly identify themselves as pro-choice (favoring fewer or no restrictions on abortion). For such voters, where a candidate stands on the issue of abortion can be the determining factor for how they vote. A person's beliefs about the proper role of the United States in world affairs and conflicts also influence how they will vote.
Political scientists have identified two types of voting that explain voter behavior. Retrospective voting refers to voting choices based on the past performance of a political party, officeholder, or administration. This type of voting evaluates candidates based on their record and the policies for which they can be seen to be responsible. A campaign ad praising a candidate's record in office appeals to this type of voting. Prospective voting refers to voting choices based on the expectations of the future performance of a political party, officeholder, or administration. This type of voting clearly comes into play with inexperienced candidates, including those running for a type of office in which they have never served, such as a member of Congress running for president.
