Nearly 80,000 transgender people may be prevented from voting in November’s midterm elections, according to a new report released Thursday from the Williams Institute at the UCLA School of Law.

According to the Williams Institute, the trans people most likely to be impacted are those living in eight states with restrictive laws that require voters to present a current photo ID: Alabama, Georgia, Indiana, Kansas, Mississippi, Tennessee, Virginia, and Wisconsin. In those states, poll workers can turn away voters if their identification does not strictly match their current name and gender presentation.

Based on population statistics and surveys of the transgender community, the Williams Institute estimated that 137,000 trans people live in those eight states. And around 57 percent of those people are unlikely to have identification that reflects their current gender and name — making over 78,000 trans people unable to vote in those eight states alone this fall.

In many of those states, there are obstacles to acquiring or updating identity documents for transgender people. In Mississippi, for example, a “religious freedom” law allows government clerks to refuse service to LGBTQ+ people if they claim doing so conflicts with their faith. In January, the Supreme Court refused to hear a challenge to the law. And trans Mississippi residents have already been turned away when trying to update identity documents: In July 2016, Lambda Legal wrote a letter to the Mississippi Department of Public Safety on behalf of a trans woman who was not only misgendered and told she wouldn’t be given a driver’s license with a female gender marker, but was also threatened with arrest if she returned to the DPS office to try again.

Due to the barriers trans people face when attempting to update their name and/or gender marker on legal documents, 46 percent of trans adults report having no identity documents that reflect their gender and name accurately. And having the wrong ID can be dangerous: 32 percent of trans people surveyed by the National Center for Transgender Equality said they’d faced negative reactions after presenting identification that didn’t match their gender presentation — including harassment, being denied services or asked to leave an establishment, and even physical assault.

But while lack of access to proper ID can be a struggle in many ways, being disenfranchised from voting in elections can have a larger impact that affects not just the LGBTQ+ community, but all voters.

“In 2016, 77,000 votes across just a few states decided the Presidential election,” says Jody Herman, a public policy scholar at the Williams Institute. “We find that 78,000 trans voters could be disenfranchised due to voter ID laws. Every single one of those votes matters.”

If it’s disturbing to think that disenfranchised trans voters in just eight states could have altered the outcome of the presidential election had they been able to vote, the larger implications of Voter ID laws are even more disconcerting.

Prior to 2006, photo ID was not required to vote in any U.S. state. Now, 34 states have some form of voter ID law, and 10 states require photo ID specifically. The laws are pushed by Republican officials like Trump’s former White House Chief of Staff Reince Priebus, who says requiring identification to vote is simply “common sense.” But studies have shown that these laws disenfranchise people of color and lower their overall voting counts. Federal judges have agreed that some voter ID laws were intended to prevent Black and Latino people from voting.

In a 2017 study conducted by the Political Science department at the University of California, San Diego, researchers found that in strict voter ID states, Latino voter turnout is 7.1 percentage points lower in general elections and 5.3 points lower in primaries than in states that don’t have these laws. The turnout gap between white voters and Black voters grows from 2.5 to 11.6 in states with strict voter ID laws. And it’s not just about race; voter ID laws were shown to alter the political shift of an election by more than doubling the turnout gap between conservative and liberal voters.

In Alabama, the NAACP is currently in court challenging the state’s voter ID law, saying that it was created to prevent low-income Black and Latino residents from voting in elections. Similar legal battles are taking place in Iowa, Texas, and Missouri, and follows a handful of lawsuits opposing voter ID laws in states across the country.

President Trump was roundly mocked in late July for falsely stating that Americans must present ID to buy groceries, but he made the mistake while campaigning for stronger voter ID laws — something he says will prevent immigrants from voting, because “only American citizens should vote in American elections.”
