States with voter ID laws have seen 'zero decrease' in turnout, NC Republican says
Should North Carolina residents have to show photo identification to vote?
Republicans who control North Carolina’s state legislature are considering the requirement, and have proposed putting a referendum on the November ballot.
Those who support the idea say it’s needed to prevent people from impersonating one another.
Critics, meanwhile, say photo ID requirements discriminate against poor people and minorities who may not have driver’s licenses or other forms of photo ID. They also say photo ID is unnecessary, since reports of voter fraud in North Carolina are rare and tend to occur not at polling sites but with mail-in ballots.
State Rep. Tim Moore, the Republican House speaker, recently defended the idea in an interview with Spectrum News. Reporter Loretta Boniti asked Moore whether an ID requirement might suppress votes.
"Not at all," Moore said in the June 7 interview. "States that have adopted voter identification laws have seen zero decrease in voter participation. In fact, most have seen an increase in voter participation."
He went on to say that, "When it comes to voter participation, it's generally dependent on what kind of cycle it is."
We decided to look at what has happened in states that did what Republicans would like to do in North Carolina. Was there no decline in voter participation, as Moore said?
Thirty-four states have laws requesting or requiring voters to show some form of identification at the polls. Seven states — Georgia, Indiana, Kansas, Mississippi, Tennessee, Virginia and Wisconsin — have what the National Conference of State Legislatures refers to as "strict photo ID" requirements.
By "strict," the NCSL means that voters in those states who don’t present acceptable photo ID must vote on a provisional ballot and then come back with an acceptable ID after Election Day for it to be counted.
Voting laws in NC
In North Carolina, voters don't have to show photo ID when they vote or register to vote. The proposed ballot question is vague, leaving it up to the legislature to fill in the details on what kinds of IDs would be needed.
The North Carolina legislature, which has been controlled by Republicans since 2011, adopted a voter ID law in 2013 that limited voting options and required voters to show photo ID at the polls. Federal appellate judges struck that law down in 2016, saying the restrictions "target African Americans with almost surgical precision."
In his interview, Moore didn’t specify what he meant by "voter ID" or "participation." Joseph Kyzer, Moore’s communications director, clarified in an email to PolitiFact that Moore was referring to total turnout.
"While fluctuations in voter participation between election cycles are common, none of the extensive studies on this issue have demonstrated that voter ID decreased total turnout in the thirty-two states that have some form of voter ID," Kyzer said.
But total turnout — the percentage of eligible voters that make it to the polls — is not the contentious point with voter ID. Turnout is higher in presidential years, an exciting governor’s race increases interest, and other factors drive turnout.
The voter ID debate hinges on whether these laws systematically put certain types of voters at a disadvantage compared to others. That was at the heart of the federal appeals court ruling.
Effects of voter ID
"Turnout alone doesn’t tell the whole story," said Myrna Perez, deputy director of the Democracy Program of the liberal-leaning Brennan Center for Justice at NYU School of Law. "The portion of the population without the ID can be suppressed, and at the same time, people who do have the ID can turn out in larger numbers."
Among the most cited and respected studies on the impact of voter ID laws was one conducted in 2014 by the U.S. Government Accountability Office, an independent, nonpartisan agency that works for Congress. The GAO did its own study while examining 10 others.
When comparing the 2008 and 2012 elections, the GAO analysis found that turnout decreases in Kansas and Tennessee "were attributable to changes in those two states’ voter ID requirements." And of the 10 studies the GAO reviewed, five found that ID requirements had no statistically significant effect on turnout; four found decreases in turnout and one found an increase in turnout.
"Although not the final word on this question, the GAO study provides credible evidence that strict ID requirements may depress turnout," said Barry Burden, director of the Elections Research Center at the University of Wisconsin.
"It remains clear that the best research on this topic does not support the idea that voter participation increases as a result of a voter ID law, with about half of studies unable to detect a statistically significant effect on turnout and the other half of studies finding a small negative effect on turnout," he added.

On the other hand, Adam Berinsky, director of the political experiments research lab at the Massachusetts Institute of Technology, said "the research findings are mixed. So ‘zero decrease’ may be going too far, but there is no clear evidence of decrease."
As for Moore’s claim of an increase in participation, "That seems clearly beyond the scope of findings from credible research," Berinsky said.
Votes blocked
Several experts pointed to a paper by Benjamin Highton, a professor at UC-Davis, as a good summary of the situation.
Highton acknowledges a lack of conclusive studies, but notes "even if we posit that voter identification laws have no influence on turnout because all those without valid identification who would otherwise vote take the necessary steps to obtain proper identification in advance of Election Day, these people do face a higher barrier to voting."
Photo ID laws are a "barrier," Highton said, and the barrier is "real, nontrivial, and unequal in impact."
Moore’s office pointed to an Atlanta Journal-Constitution article showing that turnout rose among black and Hispanic voters from 2006 to 2010 — despite adoption of a new voter ID law in 2007. But the same article noted that the ID requirements blocked some votes from being counted.
Under Georgia’s law, an in-person voter who arrives without a photo ID may cast a provisional ballot. The provisional ballot is counted only if the person returns with proper identification by the Friday following the election.
"Records show that since 2008, 2,244 provisional ballots were cast by voters lacking photo ID. Of those, 658 returned with an ID and 1,586 did not — meaning their votes did not count," the AJC reported.
North Carolina’s short-lived voter ID law yielded similar results. In the state’s 2016 presidential primary, 1,276 ballots weren’t counted because the voter didn’t bring ID to the polls, according to Josh Lawson, general counsel for the N.C. Board of Elections and Ethics Enforcement.
Of those who did not bring photo ID with them to the polls, nearly 1,100 who possessed valid IDs failed to return to their county board of elections to show their IDs before results were certified, so their votes did not count.
An algorithm developed by professors at Tufts and Harvard universities recently found that, in Texas, voters who were black and Hispanic were less likely to have IDs than whites. Their research methods are considered among the most precise for tracking voters, as explained by Wired Magazine.
Both sides point to studies
Moore’s office pointed to a mixture of academic studies, news articles and opinion columns to support his claim. They look at individual results from specific states, as well as the broad effects of voter ID on turnout.
Indiana adopted a voter ID law in 2005. The Joint Center for Political and Economic Studies, a liberal Washington think tank that focuses on issues of race, found that black turnout in the 2008 election was at a historic high after rising substantially from 2004. Hans von Spakovsky, a proponent for voter ID and senior legal fellow at the conservative Heritage Foundation think tank, noted the rise in black turnout in both Indiana and Georgia in a 2009 column.
A 2017 study by a trio of professors from UC-San Diego and Bucknell University, "Voter Identification Laws and the Suppression of Minority Votes," found "a significant drop in minority participation" in states that implemented strict voter ID laws between 2006 and 2014. But that finding was disputed in another study by five professors who argued the trio used unreliable data to reach their conclusions. (Moore’s office cited that subsequent study to support his claim that there’s no evidence photo ID laws affect voter turnout.)
Still, contrary to Moore’s "zero decrease" statement, available data suggest that voter ID can decrease voter participation.
Eitan Hersh, who is one of those five professors and also was among the developers of the algorithm used to track Texas voters, said that Moore’s statement is "misleading" since some voters struggle to obtain ID.
"At the same time, measuring an aggregate effect of ID laws is hard and there hasn’t been decisive evidence about how many people are actually deterred from these laws," Hersh said in an email. "There has also been no good evidence to suggest the laws increase turnout."
Justin Grimmer, another of the five professors, said Moore is exaggerating the research conclusions.
"The best I could say is (it’s) lacking a lot of context," Grimmer said. "Acceptable IDs are not held by everyone and disproportionately minorities and low income people don't have IDs. Therefore, if there is a mechanical deterrence effect of ID laws, then it will harm minorities. This was the line of argument used in the Texas ID law case and I find it convincing."
PolitiFact ruling
Moore said "states that have adopted voter identification laws have seen zero decrease in voter participation. In fact, most have seen an increase in voter participation."
There’s a kernel of truth in Moore’s statement, as studies haven't consistently shown a direct relationship between voter ID laws and voter participation. However, a report from the nonpartisan Government Accountability Office found some evidence that participation declines. And experts said studies don't show an increase in participation as a result of voter ID.
Moore’s claim that there has been "zero decrease" in voter participation is a misleading exaggeration. We rate his claim Mostly False.
