Flawed data flagged 7,730 people in Arkansas to be removed from voter rolls, a spokesman for the secretary of state said Friday. That data have caused headaches for county clerks, who have been left to work out what’s accurate. Some on the list are felons who have not yet taken the steps to regain their right to vote and must be kept off voter rolls, but others on the list have not committed a felony or have already had their rights restored. Interviews with a handful of county clerks show that they are removing only a fraction of those people. In Pulaski County — where nearly 2,000 of those named on the state’s list reside — about 20 percent will be removed after staff members investigated each person, said Jason Kennedy, assistant chief deputy of the clerk’s office.
