In June, the Supreme Court struck down the key enforcement mechanism of the Voting Rights Act of 1965, which mandated Justice Department review of election law changes in states and counties with a history of voting discrimination.

The state of Texas responded almost immediately by going ahead with an arduous photo ID requirement that had until the Supreme Court’s decision been blocked by federal courts.

As the Justice Department and voting rights advocates feared, Texas’ law, which went into effect on Monday, is already keeping qualified people from registering to vote. So far, only 41 of the 1.4 million people who lack an eligible voter ID have obtained a substitute “election identification certificate.” But the new requirement isn’t just preventing people who don’t have certain forms of ID from registering to vote – it’s also threatening to disenfranchise women who changed their names when they married.

Policy Mic notes that the Texas law “requires all voters to provide a photo ID that reflects their current name. If they cannot, voters must provide any of a series of other acceptable forms of identification all of which must match exactly and match the name on their birth certificate." This presents a problem for the 34 percent of women who lack an ID that shows their current name, including those who changed their names when they married:

In fact, only 66% of women have an ID that reflects their current name. If any voter is using name different than what appears on their birth certificate, the voter is required to show proof of name change by providing an original or certified copy of their marriage license, divorce decree, or court ordered name change. Photocopies aren’t accepted.

Now ask a woman who’s been married for years where her original marriage certificate is. Ask a woman who’s been divorced — maybe more than once — where all the divorce decrees are. Ask elderly women where their original birth certificate is.

Today, Think Progress reports on one Texas woman caught in this trap: a state district court judge who has been voting for nearly 50 years but whose registration was almost blocked because her drivers’ license lists her maiden name as her middle name, while her voter registration form did not:

As she told local channel Kiii News, 117th District Court Judge Sandra Watts was flagged for possible voter fraud because her driver’s license lists her maiden name as her middle name, while her voter registration form has her real middle name. This was the first time she has ever had a problem voting in 49 years. “What I have used for voter registration and for identification for the last 52 years was not sufficient yesterday when I went to vote,” she said.

Watts worried that women who use maiden names or hyphenated names may be surprised at the polls. “I don’t think most women know that this is going to create a problem,” the judge said. “That their maiden name is on their driver’s license, which was mandated in 1964 when I got married, and this. And so why would I want to use a provisional ballot when I’ve been voting regular ballot for the last 49 years?"

The Justice Department is currently suing Texas over the law  and asking a federal court to require preclearance in the future, under a section of the Voting Rights Act not affected by its recent ruling.
