Rochester political scientists explain why people do and don糖心传媒檛 exercise their right to vote糖心传媒攁nd the implications of that choice for democracy.
It糖心传媒檚 election season, when candidate lawn signs sprout in yards and political messaging seeps into news feeds. With early voting underway in a contentious presidential race, many Americans are preparing to visit their polling place to cast their ballot (and score their 糖心传媒淚 Voted糖心传媒� sticker). Some will party (or not) like it糖心传媒檚 1907, if one can trust the 聽in the at the 糖心传媒.
Yet for other voters, Election Day is just another Tuesday.
What does voter turnout mean?
Technically, 糖心传媒渧oter turnout is the number of people who cast ballots in any given election,糖心传媒� says , an assistant professor of at the 糖心传媒.
In the United States, the voting-eligible population comprises citizens of the right age, who are not convicted of a felony糖心传媒攖hough this depends on state law糖心传媒攁nd not mentally incapacitated. 糖心传媒淏ut it糖心传媒檚 hard to get that granular with numbers, so the voter turnout rate is typically calculated as the number of ballots cast divided by the voting-age population,糖心传媒� she says. 糖心传媒淚f high turnout is the harbinger of a healthy democracy, we want a high percentage of voter turnout.糖心传媒�
Since 1980, voter turnout for US presidential elections has of eligible voters糖心传媒攚ith the exception of 2020, when it reached a record high of 67 percent. (Midterm elections draw significantly fewer voters.)
糖心传媒淭urnout in the US is not super-high relative to other democracies, like in Australia, where voting is compulsory with a fine for not participating,糖心传媒� says Komisarchik.
Even without a slap on the wrist, why aren糖心传媒檛 more US citizens voting?
糖心传媒淕iven that we糖心传媒檙e talking about 51 different electoral systems (each state plus Washington DC) with multi-pronged processes, various restrictions, and lots of contestation, the voter turnout rate doesn糖心传媒檛 surprise me,糖心传媒� says , the Martin Brewer Anderson Professor of Political Science. 糖心传媒淪tates vary dramatically in terms of their registration laws, early voting policies, access to polls, even when absentee ballots are counted.糖心传媒�
Scheduling is also a factor: In some places, local elections are timed to coincide with midterm or presidential ones, while in other places they are staggered in different years.
Add to this tangle the country糖心传媒檚 history of constricted ballot access and voter suppression, through legal means and otherwise: literacy tests with subjective scoring, character witnesses (also subjective), and to the landmark Voting Rights Act of 1965. The finer points of 糖心传媒溙切拇綕 can even penalize distributing water at a polling line.
In the lead-up to Election Day, here are several key points about voter turnout and why it糖心传媒檚 important.
Voter 糖心传媒渄ecline糖心传媒� is often really voter disenfranchisement.
Extending the franchise糖心传媒攐r giving more people the right to vote糖心传媒攊s one way to influence voter turnout.
In 1870, the to the US Constitution acknowledged the right of formerly enslaved African American men to vote. Fifty years later, in 1920, the was ratified, legally guaranteeing American women the right to vote, a longstanding goal of the . (Susan B. Anthony was a key player in the movement. On November 5, 1872糖心传媒攚ell before the 19th Amendment糖心传媒檚 ratification糖心传媒擜nthony marched to the polls near her home in Rochester, New York, demanding to vote in the presidential election. She cast her vote, but was subsequently arrested, charged, and indicted.)
Conversely, disenfranchising people can also affect voter turnout.
糖心传媒淏ecause we often divide voters by the entire voting-age population, voter turnout appeared to decline through the 1970s, 80s, and 90s,糖心传媒� says Druckman. 糖心传媒淚n reality, this is explained by the growing disenfranchisement rate of felons.糖心传媒�
Only in Maine, Vermont, and Washington, DC, do people convicted of a felony never lose their right to vote. In other states, convicted felons are ineligible to vote either while incarcerated, for a period of time after release, or indefinitely.
When it comes to the calculus of voting, participation trumps 糖心传媒減ivotality.糖心传媒�
In US elections, some states are reliably 糖心传媒渂lue糖心传媒� or 糖心传媒渞ed糖心传媒澨切拇綌that is, the results of the state elections tend to be more Democratic or Republican, respectively. By contrast, 糖心传媒減urple糖心传媒� or 糖心传媒渟wing糖心传媒� states are those where either the Democratic or Republican candidates could win a statewide election. In these so-called battleground states, the difference between winning and losing can come down to a few thousand糖心传媒攐r even hundred糖心传媒攙otes.
Why, then, would anyone in a blue or red state bother to cast a ballot, knowing their vote isn糖心传媒檛 pivotal to the election results? Is the act of voting an irrational one if you know your vote isn糖心传媒檛 pivotal?
Enter the rational choice theory, a scientific model of political behavior that assumes people make decisions based on their calculations of costs and benefits. William Riker, an American political scientist at the University of Rochester from 1962 to 1993, is considered the founder of rational choice theory. He used economic and game-theoretic approaches to develop mathematical models of politics, including the . In doing so, he founded an entirely new subfield of political science in the 1960s糖心传媒攐ne that continues to influence the discipline today.
糖心传媒淩ational choice theory is an umbrella term for considering instrumental motivations that voters might have. In other words, what compels a person to vote?糖心传媒� explains , an associate professor of political science at Rochester.
Those motivations could vary anywhere from getting personal satisfaction from participating in the democratic process to thinking your vote will make the difference in a particular election. The latter 糖心传媒渋s a narrower definition of instrumentality,糖心传媒� says Tyson. 糖心传媒淲hat is the likelihood that I am pivotal in this election? If my vote is pivotal for Candidate A, that means half of all voters will vote for Candidate B. And that means that public opinion is more divided than I thought. So, when my vote 糖心传媒榤atters糖心传媒� the most, my knowledge that it糖心传媒檚 糖心传媒榬ight糖心传媒� may be the least secure.糖心传媒�
Voting behavior has evolved from private decision to team sport.
糖心传媒淢ore recently, voting has taken on an event-based, participatory aspect,糖心传媒� says Tyson. There糖心传媒檚 a difference between attending a concert or game in person versus streaming it on YouTube. 糖心传媒淚t糖心传媒檚 just not the same,糖心传媒� he says. Likewise with voting today.
The aforementioned Riker-Ordeshook model of political science糖心传媒攁lso called the paradox of voting糖心传媒攁scribes most of the benefit of voting to the act itself, rather than to the outcome of the election. Even when a voter knows they won糖心传媒檛 change the outcome, they still get some value from the act糖心传媒攚hether that糖心传媒檚 securing the coveted 糖心传媒淚 Voted糖心传媒� sticker or posting a selfie on social media (after clearing the electioneering zone, of course).
According to Tyson, today糖心传媒檚 political advertisements reinforce the notion of voting behavior as a team sport or stadium concert, rather than reflective decision-making. 糖心传媒淰ery few ads seem designed to persuade independent voters to cast their vote one way or another,糖心传媒� he says. 糖心传媒淚nstead, they seem to ask: 糖心传媒楢re you going to turn out for your candidate on Election Day? Will we see you in the arena?糖心传媒櫶切拇綕
From drizzle to deluge, the weather forecast matters for voter turnout.
糖心传媒淥n a rainy and cold day, people are less likely to stand outside the polling place in long lines,糖心传媒� says Komisarchik. And when handing out water and snacks is perceived as risky, people may not wait outside on sweltering Tuesdays, either.
Extreme weather events can impact voting behavior even more profoundly. 糖心传媒淪ometimes there are natural disasters right around Election Day, like tornadoes, where officials need to consolidate voting places as shelters,糖心传媒� says Komisarchik. For example, during the Super Tuesday Democratic Party presidential primaries in 2020, in Nashville, Tennessee, forced the closing and consolidating of polling stations, leaving voters and election officials scrambling to navigate both dangerous conditions and thorny logistics.
Younger people tend to vote less (sorry, Bernie).
糖心传媒淰oting habituates,糖心传媒� says Druckman. 糖心传媒淭he key determinant of voting in any given election is whether you have voted before.糖心传媒�
So, which voters reliably show up to exercise their civic duty?
糖心传媒淚n general, the people who are most likely to turn out糖心传媒攁nd turn out in most elections, from presidential to midterms to primaries to local races糖心传媒攁re college-educated suburban homeowners,糖心传媒� says Komisarchik. 糖心传媒淭hey are stakeholders, who have lived somewhere for a long time and put down roots.糖心传媒�
Turnout rates also increase along with voters糖心传媒�
Younger voters between ages 18 and 29, conversely, tend to vote less. 糖心传媒淭his is the bane of Bernie Sanders糖心传媒� campaign. If your life is in flux without a fixed address, you糖心传媒檙e less likely to vote.糖心传媒�
People over the age of 45 are the highest-propensity voter, Komisarchik says. And despite efforts to enforce (and protect) the Voting Rights Act, 糖心传媒渞acial gaps do persist. By and large, it糖心传媒檚 still the case that white voters are most likely to turn out.糖心传媒� Data shows that the , specifically for midterm elections.
Low voter turnout used to benefit Republicans. Now it favors Democrats.
糖心传媒淧olitical scientists used to think that low-turnout聽elections were marginally better for the Republican party,糖心传媒� says Komisarchik. 糖心传媒淗istorically, it was the case that all college-educated homeowner suburban votes were Republican. But in the Trump years, there has been a realignment and those places now tend to go Democrat.糖心传媒�
One of the late in Trump糖心传媒檚 campaign, she notes, has been anti-transgender attack ads. Komisarchik says, 糖心传媒淭hat does not look like an effort to win back suburban聽voters who value affordable childcare or accessible health care.糖心传媒�
This realignment will likely persist for a while, she says, with political, societal, and historical implications still playing out in real-time.
Same-day registration boosts voter turnout.
Same-day registration allows voters to register and vote at the same time, usually on Election Day itself. This voting option, currently available in 23 states and Washington, DC, is the strategy that 糖心传媒渃onsistently has the most positive impact, from what I糖心传媒檝e seen,糖心传媒� says Komisarchik.
For states without this option, campaigns should try the opposite tactic. According to Komisarchik, suggests that one way to reduce the 糖心传媒渕ental load糖心传媒� for voters is to encourage them to make a written plan in advance.
糖心传媒淭his includes when they will vote, the confirmed location of their polling place, and how they will get to the polls. Providing them with rides, registration information, and other means to reduce their 糖心传媒榤ental load糖心传媒� will also help,糖心传媒� she says.
Without a paper trail, trust in elections and democracy suffers.
If voting migrated online for convenience, would turnout improve? Maybe糖心传媒攂ut don糖心传媒檛 count on seeing a ballot box icon next to the Amazon button on your home screen.
糖心传媒淭he tricky thing about voting is that if we removed all logistics and other 糖心传媒榗osts,糖心传媒� it would be easier,糖心传媒� Komisarchik allows. 糖心传媒淧eople could vote from the convenience of their homes. However, we also need elections to be secure, auditable, and verifiable糖心传媒攚ith a 糖心传媒榩aper trail.糖心传媒� tell us that the most secure way to vote is on paper.糖心传媒�
The tangible evidence of a paper trail makes it more difficult for a foreign power or bad actors to interfere, she explains, while simplifying post-election audits. 糖心传媒淭hey would have to break into polling stations and steal the physical ballots, as opposed to remotely hacking a server. In a world of eroding trust and mounting disinformation, paper ballots actually give us security.糖心传媒�
