“This anti-voter fraud program gets it wrong over 99 percent of the time. The GOP wants to take it nationwide.”

At the inaugural meeting of President Trump’s Election Integrity Commission on Wednesday, commission Vice-Chairman Kris Kobach of Kansas praised a data collection program run by his state as a model for a national effort to root out voter fraud.

States participating in the program, known as the Interstate Crosscheck System, send their voter registration files to Kansas. Kansas election authorities compare these files to those from other states. Each participating state receives back a list of their voter registrations that match the first name, last name and date of birth of a voter in another state. States may act upon the findings as they wish, although Crosscheck provides some guidelines for purging voter registrations from the rolls.

In theory, the program is supposed to detect possible cases of people voting in multiple locations. But academics and states that use the program have found that its results are overrun with false positives, creating a high risk of disenfranchising legal voters. A statistical analysis of the program published earlier this year by researchers at Stanford, Harvard, UPenn and Microsoft, for instance, found that Crosscheck “would eliminate about 200 registrations used to cast legitimate votes for every one registration used to cast a double vote.”
