There are reports that machines were down in Scranton, Pennsylvania earlier today, prompting a judge to order polling places stay open later. There have been some tweets circulating that made this out to be suspicious, but these kinds of malfunctions happen. To be clear, the machines that had problems were optical scanners, into which voters insert their hand-marked paper ballots for tabulation. As Eddie Perez, an election technology expert, explained in a tweet thread, these devices are built with an emergency slot to store ballots for later tabulation in the event they break down because, well, it happens!
