WASHINGTON (AP) More than one in 10 voters could cast ballots on paperless voting machines in the 2020 general election, according to a new analysis, leaving their ballots more vulnerable to hacking.

A study released by the Brennan Center for Justice at NYU School of Law on Tuesday evaluates the state of the countrys election security six months before the New Hampshire primary and concludes that much more needs to be done. While there has been significant progress by states and the federal government since Russian agents targeted U.S. state election systems ahead of the 2016 presidential election, the analysis notes that many states have not taken all of the steps needed to ensure that doesnt happen again.

The report also notes that around a third of all local election jurisdictions were using voting machines that are at least a decade old, despite recommendations they be replaced after 10 years. The Associated Press reported last month that many election systems are running on old Windows 7 software that will soon be outdated.

We should replace antiquated equipment, and paperless equipment in particular, as soon as possible, the report recommends.
