We'll be on the lookout all day for issues across the country related to voter suppression & voter access. There's already plenty of buzz about potential spread of misinformation, as well as issues falling in the category of unforeseen events, non-functioning machines, etc.
Rhode Island Board of Elections tweeted this morning that "several polls opened a bit late due to pollworkers not reporting for duty or issues entering a complex password to start the voting machine."
And in Pittsburgh, the Carnegie Library polling site was delayed in getting up and running due to a medical emergency. Emergency paper ballots were sent to the location.
