Verified Voting Blog: Verified Voting Statement on Ballot Marking Devices and Risk-limiting Audits
This statement is intended to clarify Verified Voting’s position regarding the use of ballot-marking devices (BMDs) in elections, and the use of risk-limiting audits (RLAs). It is approved by the President, Board of Directors, and Staff of Verified Voting.
Ballot-marking devices
Verified Voting believes that voters should vote on paper ballots, but we recognize an important distinction between hand-marked and machine-marked ballots. Hand-marked paper ballots are not subject to inaccuracies or manipulation from software bugs or malicious code. In contrast, machine-marked paper ballots produced using BMDs might not accurately capture voter intent if the software or ballot configuration is buggy or malicious.
Verified Voting specifically opposes the purchase and deployment of new voting systems in which all in-person voters in a polling place are expected to use BMDs. The trustworthiness of an election conducted using BMDs depends critically on how many voters actually verify their ballots, and how carefully they do it. All voters who vote on BMDs should be made aware of the importance of carefully and conscientiously verifying their ballots before casting them, and should be actively encouraged to do so. However, empirical research thus far shows that few voters using BMDs carefully verify their printed ballots. Moreover, if voters do verify BMD-marked ballots and find what they believe are discrepancies, there is no reliable way to resolve whether the voters made mistakes or the BMDs did. For these and other reasons (such as cost) Verified Voting recommends that the use of BMDs be minimized.
