The study also found that such laws have “no negative effect” on voter registration or voter turnout either overall or for any specific group, whether defined by race, gender, age, or party affiliation.
The findings contradict a major assertion made by many election-oriented groups and Democratic politicians who believe that voter ID laws are a source of voter suppression. Voter ID laws and other contentious election integrity measures usually occur in states with Republican-controlled legislatures, making it a partisan issue.
Authors Enrico Cantoni of the University of Bologna and Vincent Pons of Harvard Business School analyzed elections spanning eight years and used a methodology involving 1.3 billion voting observations.
“These results hold through a large number of specifications and cannot be attributed to mobilization against the laws, measured by campaign contributions and self-reported political engagement,” the authors said.
However, the study also found that voter ID requirements have no effect on voter fraud, leading the study’s authors to conclude that “efforts to reform voter ID laws may not have much impact on elections.”
A spokesman for the Public Interest Legal Foundation (PILF), a conservative election integrity organization, said the robust voting study is just the latest research to confirm that voter ID does not harm the voting public, though he questioned the findings about voter fraud.
“Voter ID is often the last line of defense against voter fraud at the polls,” said PILF spokesman Logan Churchwell in a phone interview, indicating that other forms of fraud, such as absentee-ballot fraud, are easier to commit.
Broad-based Support
Not all voter ID laws are the same. While 35 states have laws requesting or requiring voters to show some form of identification at the polls, only seven states have “strict photo ID,” the most stringent form of the laws.Failure to do so doesn’t mean an otherwise eligible voter will be permanently denied. Rather, voters without identification are required to cast a provisional ballot and sometimes return to an elections office within several days after Election Day with proper ID.
Despite their draconian reputation—whether strict photo ID, non-photo ID, or laws requesting identification but not requiring it—survey polls have consistently shown strong broad-based support for the measures.
A Campaign Issue
Stacey Abrams, a rising star in the Democratic Party, has staked her career on voting rights, or alternatively, voter suppression.Less than a month prior to her narrow election loss in November to Georgia Gov. Brian Kemp, Abrams declared Georgia’s strict photo ID law was meant to “scare people out of voting.”
According to public records, Abrams raised $12.5 million from 2013 to 2016 through two voting-rights nonprofits she founded.
