Kansas Secretary of State Kris Kobach is a right-wing activist who has championed anti-immigrant and voter suppression efforts around the country and has helped to insert right-wing rhetoric into recent Republican platforms. As Miranda reported this month, Kobach is pushing his fellow Republicans to adopt legislation modeled after the disastrously restrictive voting law he helped push through in Kansas. The September 8 issue of Rolling Stone looks at one of Kobach’s ventures in “The GOP’s Stealth War Against Voters.”

The Rolling Stone story by journalist and author Greg Palast examines Crosscheck, a Kobach project that Palast calls “the culmination of a decade-long Republican effort to disenfranchise voters under the guise of battling voter fraud.” The Interstate Voter Registration Crosscheck Program is ostensibly designed to target a virtually nonexistent form of voter fraud. In reality, it helps promote the Right Wing’s bogus voter fraud narrative, which in turn provides justification for otherwise unjustifiable laws that restrict voting. In the worst case scenario, Crosscheck could lead to thousands of people, predominantly people of color and young voters, being wrongly purged from voting rolls in advance of November’s election.

Crosscheck compares voter registration lists in different states to identify individuals who are registered in more than one place. Theoretically, it requires matches on a voter’s first, middle and last name, along with birth date and the final four digits of a social security number, but in reality, it doesn’t always work as advertised. As we noted a couple years ago, Crosscheck’s data was so unreliable that Florida and Oregon dropped out of the program.

Palast says he was able to get his hands on Crosscheck lists from Virginia, Georgia and Washington state, and found that the lists often lacked a middle-name match and misidentified fathers and sons as the same voter. He cites database expert Mark Swedlund, who criticizes Crosscheck’s “childish methodology.” He also notes that U.S. Census data indicates that people of color are statistically more likely to have last names in common, leading to an “astonishing” inherent bias in the results, with “one in six Hispanics, one in seven Asian-Americans, and one in nine African Americans in Crosscheck states landing on the list.” And Donald Trump complains the election is rigged against him!

“God forbid your name is Garcia, of which there are 858,000 in the U.S., and your first name if Joseph or Jose,” says Swedlund. “You’re probably suspected of voting in 27 states.”

It is up to each state to decide how it uses the data from Crosscheck; some send the lists to county officials who don’t have the resources to verify their accuracy. Rolling Stone reports that Crosscheck “has flagged close to half a million voters” in Ohio, and that 41,000 people were knocked off voting rolls in Virginia when it was under Republican control.

Even if state and local officials don’t end up using the data to initiate major purges, Crosscheck’s inflated numbers can be used to buttress false right-wing claims that voter fraud is a big problem. That mythology has been particularly damaging in the aftermath of rulings from conservative justices on the Supreme Court dismantling key Voting Rights Act protections, which allowed Republican officials in many states to pass laws aimed at making it harder for some people, particularly people of color and young people, to register and vote. And, says Palast, gutting the Voting Rights Act also meant dropping the requirement for covered states to keep racial data on voters, making it harder to document discriminatory practices.
