Conservative proponents have argued for photo ID mandates by claiming that widespread voter impersonation exists in America, despite overwhelming evidence to the contrary. While defending its photo ID law before the Supreme Court, Indiana was unable to cite a single instance of actual voter impersonation at any point in its history. Likewise, in Kansas, there were far more reports of U.F.O. sightings than allegations of voter fraud in the past decade. These theories of systematic fraud are really unfounded fears being exploited to threaten the franchise.
