Hand-marked Ballots

Ballot-Marking Devices (BMDs) Cannot Assure the Will of the Voters

January, 2020

Abstract

Computers, including all modern voting systems, can be hacked and misprogrammed. The scale and complexity of U.S. elections may require the use of computers to count ballots, but election integrity requires a paper-ballot voting system in which, regardless of how they are initially counted, ballots can be re- counted by hand to check whether election outcomes have been altered by buggy or hacked software. Furthermore, secure voting systems must be able to recover from any errors that might have occurred.
