This System Catches Vote Fraud and the Wrath of Critics
"Crosscheck is a computer system designed to detect fraud by finding matches in voter registration lists shared by dozens of states and thereby detecting suspected double voters.
But experts warn that Kobach could be laying the groundwork for voter suppression by using the presidential panel as a vehicle to push for the creation of a national version of the Crosscheck program. Critics fear that could lead to the widespread purging of eligible voters from the rolls because of false positive matches.
'What Crosscheck does a very bad job of is going from dual registrations to dual voting,' said Mark Johnson, an election law professor at the University of Kansas."
