Balloting covers the full lifecycle of a ballot: its design, its production, the way a voter marks it, the way it is cast, the way it is secured, and the way it is ultimately processed for tabulation. Each step in that lifecycle is a place where design decisions, accessibility considerations, and security controls come together.
Why this category matters for election security is that a ballot is the physical embodiment of voter intent. A misdesigned ballot can confuse voters and produce undervotes. An inaccessible ballot can deny equal participation. A ballot that is not properly secured between precinct and tabulation can be lost, damaged, or tampered with. The whole machinery of election administration exists to ensure that what voters marked is what gets counted.
Ballot design is a discipline in its own right. The principles of clear typography, intuitive layout, and consistent positioning of contests have been studied and codified. The use of color, the placement of instructions, the handling of write-in candidates, the treatment of overvotes and undervotes. These are not aesthetic choices. They are accessibility and accuracy choices, with security implications.
The terminology in this category covers the entire ballot lifecycle. The concepts here describe what happens between the moment a voter enters the booth and the moment a ballot is scanned for counting.
Key Concepts
Ballot
The physical or electronic medium on which a voter records their choices in an election.
Overvote
A condition in which a voter marks more choices for a contest than are permitted, resulting in the ballot or contest not being counted.
Undervote
A condition in which a voter marks fewer choices for a contest than are available.
Ballot Marking Device
A device that allows voters to mark their choices on an electronic interface, then prints a human-readable paper ballot.
Provisional Ballot
A ballot cast by a voter whose eligibility is unresolved at the time of voting, held separately and counted only if eligibility is later confirmed.
How These Terms Relate
These concepts together describe the journey of a ballot from design through tabulation. Balloting is the most visible part of election administration: it is what voters see and touch and interact with. The terminology here covers every step of that interaction. The unifying theme is that every choice, from the typography of the ballot to the handling of overvotes, has implications for accessibility, accuracy, and trust. None of these are aesthetic decisions in isolation.
