Voter roll
Definition
A voter roll, or registration list, is the official record of everyone registered to vote in a jurisdiction. Election officials use it to determine who can vote, at which precinct, and on which ballot style, updating it continually to add, correct, or remove entries.1
Why it matters
The roll is the single gate every voter must clear before their ballot counts, so errors or manipulation in list maintenance can quietly disenfranchise eligible people without any visible rule change. Because maintenance happens routinely and out of public view, it's an easy place to bury a partisan thumb on the scale.
Seen in the wild
The federal Election Assistance Commission reported that over 19 million voters were removed from voter rolls nationwide between 2020 and 2022, a 21% increase over the prior two-year period, reflecting both routine cleanup and more aggressive state-level purge programs.2
