The drumbeat of election rigging and foreign hacking of voting machines have energized ongoing efforts to develop a new model of digital election equipment designed to produce instantly verifiable results and dual records for security. Election experts say this emerging system, one of three publicly funded voting machine projects across the country, shows potential to help restore confidence in the country’s election infrastructure, most of which hasn’t been updated in more than a decade. “It’s the hardest thing I’ve ever done in my life. It’s taken years and years to get it done,” said Dana DeBeauvoir, the Travis County clerk and leader of the voting machine project. “Now that we’ve had this election, there’s renewed interest.” A prototype of the system, dubbed STAR Vote, sits in an engineering lab at Rice University, and bidding is open for manufacturers who want to produce it wholesale. Similar efforts to innovate voting systems are in the works in Los Angeles and San Francisco. “County clerks in these jurisdictions are the rock stars of running elections,” said Joe Kiniry, CEO of Free & Fair, an election systems supplier currently bidding on contracts to manufacture the designs of both Travis and Los Angeles counties. “If they have success in what they do, it will have, in my opinion, a massive impact on the whole U.S.”
