Paperless electronic voting systems have become less common in the United States since 2008, as some state and local governments have added printers to their touch-screen machines, or switched to systems that use paper ballots.
In Virginia, wealthier counties are more likely to use new, paper-based voting systems. Poorer counties are more likely to still use aging touch-screen systems that don’t provide a paper backup.
