A little-known program run by Kansas Secretary of State Kris Kobach goes through more than 100 million voter records from states across the nation. Called Interstate Crosscheck, or “The Kansas Project,” the program compares voter registration records from one state with 27 other participating states to check for duplicate voter registrations and possible double voting. The goal of the program is to clear up registration rolls, Kobach said. Nearly all double registrations are unintentional, resulting from a person moving from one state to another and re-registering to vote, Kobach says. But the computer program drills down further to try to find voters who may have voted in two separate states, he said. It’s a program that Kobach’s office provides for free. “It’s a state-run program that Kansas has developed and it’s a service for the whole country,” Kobach said. The project has generated some controversy. Earlier this month, Republican officials in North Carolina, a key battleground state, said the Interstate Crosscheck uncovered proof of widespread voter fraud. But after those initial reports, officials have walked back those assertions and were focusing on investigating a much smaller number of potential cases.
“They chose to make public the number of potential double voters,” Kobach said of North Carolina officials.
Kobach said the number of potential double voters — those whose names and dates of birth match up in two states — is always much larger than “likely double voters,” whose first and last names, dates of birth and last four digits of their Social Security numbers matched with a voter registered in another state.
But because of Kobach’s partisan background, as former Kansas Republican Party chairman, and his push nationwide for photo ID laws to vote and proof of citizenship to register to vote, his work in this area has been suspect among some Democrats in other states.
