Individual voters should NEVER have more than one (1) active ballot. If this occurs, there is a risk that human error by an election official will result in a voter having more than one ballot counted.
Virginia has 226 individuals with two or more active ballots according to the Daily Absentee List file as of 28 October, 6 AM. This is occurring in nearly half of the Localities in Virginia – 59 out of 133.
This is a process issue – either procedural, or ballot tracking. The process should make it impossible for more than one vote to be counted.
It is possible that these will be caught before they get counted … but mistakes are made when people get overloaded or distracted. Process software should prevent the possibility of this “defect” occurring to prevent the perception of malfeasance.
