Forbes has seen numerous reports of broken machines causing epic queues and peeving voters. One of the more concerning tales came from New Jersey, where one voter complained not only of machines being broken but claimed an official decided to say maybe Russians did it". If an official did say those words, whether in seriousness or in jest, it'd have been unwise given fears around Russia's hacking of the election, following the breach of the Democratic National Committee earlier this year. Many took to Twitter to complain about broken machines, including those voting in Michigan, North Carolina, Texas, Columbia and San Francisco. Most complaints have come from New York and Detroit. ProPublica also reported issues across Illinois, Kentucky and Ohio. The Tennessean reported issues ... too. A spokesperson for the Department of Homeland Security (DHS) [stated] the department has been offering cybersecurity assistance to state, county and local election agencies, and found vulnerabilities during system scans, though wouldn't disclose their nature or provenance. Voting machines have always been vulnerable, said Matt Bernhard ... an expert on the security of electoral systems. "This year isn't that different, other than I'm expecting higher turnout which may stress the infrastructure more," added Bernhard, who yesterday released a report highlighting how different areas of the U.S. use poorly-protected machines.
