2016 Postmortem

The data is processed through a system called the Interstate Voter Registration Crosscheck Program, which is being promoted by a powerful Republican operative, and its lists of potential duplicate voters are kept confidential. But Rolling Stone obtained a portion of the list and the names of 1 million targeted voters. According to our analysis, the Crosscheck list disproportionately threatens solid Democratic constituencies: young, black, Hispanic and Asian-American voters – with some of the biggest possible purges underway in Ohio and North Carolina, two crucial swing states with tight Senate races.

The Virginia list was a revelation. In all, 342,556 names were listed as apparently registered to vote in both Virginia and another state as of January 2014. Thirteen percent of the people on the Crosscheck list, already flagged as inactive voters, were almost immediately removed, meaning a stunning 41,637 names were "canceled" from voter rolls, most of them just before Election Day.

We were able to obtain more lists – Georgia and Washington state, the total number of voters adding up to more than 1 million matches – and Crosscheck's results seemed at best deeply flawed. We found that one-fourth of the names on the list actually lacked a middle-name match. The system can also mistakenly identify fathers and sons as the same voter, ignoring designations of Jr. and Sr. A whole lot of people named "James Brown" are suspected of voting or registering twice, 357 of them in Georgia alone. But according to Crosscheck, James Willie Brown is supposed to be the same voter as James Arthur Brown. James Clifford Brown is allegedly the same voter as James Lynn Brown.
