Quoted: Barry Burden, director of the Elections Research Center at the University of Wisconsin-Madison, said removing voters from the rolls because they are believed to have moved would more likely affect Democratic voters because they are more likely to move frequently.
“Mainly because they are younger, supporters of Democratic candidates tend to change their residences more often,” he said by email. “As a result, their voter registrations are more likely to be out of date, and they are more likely to be targets of efforts to clean up the rolls.”
