A group of Texas voters seeking to stop the use of paperless electronic voting machines reached a dead end on Friday; the Texas Supreme Court ruled that their suits could not proceed without evidence that they have been personally harmed.
Texas has been using direct-recording electronic (DRE) voting machines for more than a decade. In 2006, a coalition of voters led by the Austin NAACP sued to stop Travis County from using the eSlate, a DRE machine made by Austin-based Hart InterCivic. (Hart does offer a printer as an optional component of its system.) The voters claimed the machines were insecure and did not allow meaningful recounts.
Travis County disagreed. In a FAQ on the county's voting website, officials answered questions about paper trails and security.
Q: Some computer experts claim that there is no way to audit the vote without a paper trail. Does this system have paper backup?
A: This system provides voters with confidence that their vote will be counted as they intended. First, the voting device provides each voter with a summary of all votes, alerting the voter of any skipped races, and allowing the voter to make changes. The voter has visual confirmation that the vote was cast exactly as intended. To ensure the votes are recorded correctly, the system is publicly tested and validated before, during, after each election to ensure that votes are counted and reported as they are cast. There are many security features designed to test procedures, equipment and software. Finally, the system can print out all Cast Vote Records should that be required for a recount.
In other words, the county has foregone a real paper trail, but it can simply print all the vote records in the machine's memory on slips of paper at a later date. Since the concern in most such cases would be about whether the recorded votes are accurate—not, say, whether the computer was adding them up properly—this feature is largely meaningless. (A real paper trail prints a "receipt" under glass that voters can see before leaving the voting station.)
